                   Server Side Public License
                   VERSION 1, OCTOBER 16, 2018

                  Copyright © 2018 MongoDB, Inc.

Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.

                     TERMS AND CONDITIONS

0. Definitions.

“This License” refers to Server Side Public License.

“Copyright” also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.

“The Program” refers to any copyrightable work licensed under this
License.  Each licensee is addressed as “you”. “Licensees” and
“recipients” may be individuals or organizations.

To “modify” a work means to copy from or adapt all or part of the work in
a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a “modified version” of the
earlier work or a work “based on” the earlier work.

A “covered work” means either the unmodified Program or a work based on
the Program.

To “propagate” a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

To “convey” a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through a
computer network, with no transfer of a copy, is not conveying.

An interactive user interface displays “Appropriate Legal Notices” to the
extent that it includes a convenient and prominently visible feature that
(1) displays an appropriate copyright notice, and (2) tells the user that
there is no warranty for the work (except to the extent that warranties
are provided), that licensees may convey the work under this License, and
how to view a copy of this License. If the interface presents a list of
user commands or options, such as a menu, a prominent item in the list
meets this criterion.

1. Source Code.

The “source code” for a work means the preferred form of the work for
making modifications to it. “Object code” means any non-source form of a
work.

A “Standard Interface” means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that is
widely used among developers working in that language.  The “System
Libraries” of an executable work include anything, other than the work as
a whole, that (a) is included in the normal form of packaging a Major
Component, but which is not part of that Major Component, and (b) serves
only to enable use of the work with that Major Component, or to implement
a Standard Interface for which an implementation is available to the
public in source code form. A “Major Component”, in this context, means a
major essential component (kernel, window system, and so on) of the
specific operating system (if any) on which the executable work runs, or
a compiler used to produce the work, or an object code interpreter used
to run it.

The “Corresponding Source” for a work in object code form means all the
source code needed to generate, install, and (for an executable work) run
the object code and to modify the work, including scripts to control
those activities. However, it does not include the work's System
Libraries, or general-purpose tools or generally available free programs
which are used unmodified in performing those activities but which are
not part of the work. For example, Corresponding Source includes
interface definition files associated with source files for the work, and
the source code for shared libraries and dynamically linked subprograms
that the work is specifically designed to require, such as by intimate
data communication or control flow between those subprograms and other
parts of the work.

The Corresponding Source need not include anything that users can
regenerate automatically from other parts of the Corresponding Source.

The Corresponding Source for a work in source code form is that same work.

2. Basic Permissions.

All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program, subject to section 13. The
output from running a covered work is covered by this License only if the
output, given its content, constitutes a covered work. This License
acknowledges your rights of fair use or other equivalent, as provided by
copyright law.  Subject to section 13, you may make, run and propagate
covered works that you do not convey, without conditions so long as your
license otherwise remains in force. You may convey covered works to
others for the sole purpose of having them make modifications exclusively
for you, or provide you with facilities for running those works, provided
that you comply with the terms of this License in conveying all
material for which you do not control copyright. Those thus making or
running the covered works for you must do so exclusively on your
behalf, under your direction and control, on terms that prohibit them
from making any copies of your copyrighted material outside their
relationship with you.

Conveying under any other circumstances is permitted solely under the
conditions stated below. Sublicensing is not allowed; section 10 makes it
unnecessary.

3. Protecting Users' Legal Rights From Anti-Circumvention Law.

No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article 11
of the WIPO copyright treaty adopted on 20 December 1996, or similar laws
prohibiting or restricting circumvention of such measures.

When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention is
effected by exercising rights under this License with respect to the
covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's users,
your or third parties' legal rights to forbid circumvention of
technological measures.

4. Conveying Verbatim Copies.

You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice; keep
intact all notices stating that this License and any non-permissive terms
added in accord with section 7 apply to the code; keep intact all notices
of the absence of any warranty; and give all recipients a copy of this
License along with the Program.  You may charge any price or no price for
each copy that you convey, and you may offer support or warranty
protection for a fee.

5. Conveying Modified Source Versions.

You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the terms
of section 4, provided that you also meet all of these conditions:

  a) The work must carry prominent notices stating that you modified it,
  and giving a relevant date.

  b) The work must carry prominent notices stating that it is released
  under this License and any conditions added under section 7. This
  requirement modifies the requirement in section 4 to “keep intact all
  notices”.

  c) You must license the entire work, as a whole, under this License to
  anyone who comes into possession of a copy. This License will therefore
  apply, along with any applicable section 7 additional terms, to the
  whole of the work, and all its parts, regardless of how they are
  packaged. This License gives no permission to license the work in any
  other way, but it does not invalidate such permission if you have
  separately received it.

  d) If the work has interactive user interfaces, each must display
  Appropriate Legal Notices; however, if the Program has interactive
  interfaces that do not display Appropriate Legal Notices, your work
  need not make them do so.

A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work, and
which are not combined with it such as to form a larger program, in or on
a volume of a storage or distribution medium, is called an “aggregate” if
the compilation and its resulting copyright are not used to limit the
access or legal rights of the compilation's users beyond what the
individual works permit. Inclusion of a covered work in an aggregate does
not cause this License to apply to the other parts of the aggregate.

6. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these
ways:

  a) Convey the object code in, or embodied in, a physical product
  (including a physical distribution medium), accompanied by the
  Corresponding Source fixed on a durable physical medium customarily
  used for software interchange.

  b) Convey the object code in, or embodied in, a physical product
  (including a physical distribution medium), accompanied by a written
  offer, valid for at least three years and valid for as long as you
  offer spare parts or customer support for that product model, to give
  anyone who possesses the object code either (1) a copy of the
  Corresponding Source for all the software in the product that is
  covered by this License, on a durable physical medium customarily used
  for software interchange, for a price no more than your reasonable cost
  of physically performing this conveying of source, or (2) access to
  copy the Corresponding Source from a network server at no charge.

  c) Convey individual copies of the object code with a copy of the
  written offer to provide the Corresponding Source. This alternative is
  allowed only occasionally and noncommercially, and only if you received
  the object code with such an offer, in accord with subsection 6b.

  d) Convey the object code by offering access from a designated place
  (gratis or for a charge), and offer equivalent access to the
  Corresponding Source in the same way through the same place at no
  further charge. You need not require recipients to copy the
  Corresponding Source along with the object code. If the place to copy
  the object code is a network server, the Corresponding Source may be on
  a different server (operated by you or a third party) that supports
  equivalent copying facilities, provided you maintain clear directions
  next to the object code saying where to find the Corresponding Source.
  Regardless of what server hosts the Corresponding Source, you remain
  obligated to ensure that it is available for as long as needed to
  satisfy these requirements.

  e) Convey the object code using peer-to-peer transmission, provided you
  inform other peers where the object code and Corresponding Source of
  the work are being offered to the general public at no charge under
  subsection 6d.

A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be included
in conveying the object code work.

A “User Product” is either (1) a “consumer product”, which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, “normally used” refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

“Installation Information” for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.

If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as part
of a transaction in which the right of possession and use of the User
Product is transferred to the recipient in perpetuity or for a fixed term
(regardless of how the transaction is characterized), the Corresponding
Source conveyed under this section must be accompanied by the
Installation Information. But this requirement does not apply if neither
you nor any third party retains the ability to install modified object
code on the User Product (for example, the work has been installed in
ROM).

The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access
to a network may be denied when the modification itself materially
and adversely affects the operation of the network or violates the
rules and protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in
accord with this section must be in a format that is publicly documented
(and with an implementation available to the public in source code form),
and must require no special password or key for unpacking, reading or
copying.

7. Additional Terms.

“Additional permissions” are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall be
treated as though they were included in this License, to the extent that
they are valid under applicable law. If additional permissions apply only
to part of the Program, that part may be used separately under those
permissions, but the entire Program remains governed by this License
without regard to the additional permissions.  When you convey a copy of
a covered work, you may at your option remove any additional permissions
from that copy, or from any part of it. (Additional permissions may be
written to require their own removal in certain cases when you modify the
work.) You may place additional permissions on material, added by you to
a covered work, for which you have or can give appropriate copyright
permission.

Notwithstanding any other provision of this License, for material you add
to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:

  a) Disclaiming warranty or limiting liability differently from the
  terms of sections 15 and 16 of this License; or

  b) Requiring preservation of specified reasonable legal notices or
  author attributions in that material or in the Appropriate Legal
  Notices displayed by works containing it; or

  c) Prohibiting misrepresentation of the origin of that material, or
  requiring that modified versions of such material be marked in
  reasonable ways as different from the original version; or

  d) Limiting the use for publicity purposes of names of licensors or
  authors of the material; or

  e) Declining to grant rights under trademark law for use of some trade
  names, trademarks, or service marks; or

  f) Requiring indemnification of licensors and authors of that material
  by anyone who conveys the material (or modified versions of it) with
  contractual assumptions of liability to the recipient, for any
  liability that these contractual assumptions directly impose on those
  licensors and authors.

All other non-permissive additional terms are considered “further
restrictions” within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further restriction,
you may remove that term. If a license document contains a further
restriction but permits relicensing or conveying under this License, you
may add to a covered work material governed by the terms of that license
document, provided that the further restriction does not survive such
relicensing or conveying.

If you add terms to a covered work in accord with this section, you must
place, in the relevant source files, a statement of the additional terms
that apply to those files, or a notice indicating where to find the
applicable terms.  Additional terms, permissive or non-permissive, may be
stated in the form of a separately written license, or stated as
exceptions; the above requirements apply either way.

8. Termination.

You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or modify
it is void, and will automatically terminate your rights under this
License (including any patent licenses granted under the third paragraph
of section 11).

However, if you cease all violation of this License, then your license
from a particular copyright holder is reinstated (a) provisionally,
unless and until the copyright holder explicitly and finally terminates
your license, and (b) permanently, if the copyright holder fails to
notify you of the violation by some reasonable means prior to 60 days
after the cessation.

Moreover, your license from a particular copyright holder is reinstated
permanently if the copyright holder notifies you of the violation by some
reasonable means, this is the first time you have received notice of
violation of this License (for any work) from that copyright holder, and
you cure the violation prior to 30 days after your receipt of the notice.

Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.

9. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a
copy of the Program. Ancillary propagation of a covered work occurring
solely as a consequence of using peer-to-peer transmission to receive a
copy likewise does not require acceptance. However, nothing other than
this License grants you permission to propagate or modify any covered
work. These actions infringe copyright if you do not accept this License.
Therefore, by modifying or propagating a covered work, you indicate your
acceptance of this License to do so.

10. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives
a license from the original licensors, to run, modify and propagate that
work, subject to this License. You are not responsible for enforcing
compliance by third parties with this License.

An “entity transaction” is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered work
results from an entity transaction, each party to that transaction who
receives a copy of the work also receives whatever licenses to the work
the party's predecessor in interest had or could give under the previous
paragraph, plus a right to possession of the Corresponding Source of the
work from the predecessor in interest, if the predecessor has it or can
get it with reasonable efforts.

You may not impose any further restrictions on the exercise of the rights
granted or affirmed under this License. For example, you may not impose a
license fee, royalty, or other charge for exercise of rights granted
under this License, and you may not initiate litigation (including a
cross-claim or counterclaim in a lawsuit) alleging that any patent claim
is infringed by making, using, selling, offering for sale, or importing
the Program or any portion of it.

11. Patents.

A “contributor” is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The work
thus licensed is called the contributor's “contributor version”.

A contributor's “essential patent claims” are all patent claims owned or
controlled by the contributor, whether already acquired or hereafter
acquired, that would be infringed by some manner, permitted by this
License, of making, using, or selling its contributor version, but do not
include claims that would be infringed only as a consequence of further
modification of the contributor version. For purposes of this definition,
“control” includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to make,
use, sell, offer for sale, import and otherwise run, modify and propagate
the contents of its contributor version.

In the following three paragraphs, a “patent license” is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To “grant” such a patent license to a party
means to make such an agreement or commitment not to enforce a patent
against the party.

If you convey a covered work, knowingly relying on a patent license, and
the Corresponding Source of the work is not available for anyone to copy,
free of charge and under the terms of this License, through a publicly
available network server or other readily accessible means, then you must
either (1) cause the Corresponding Source to be so available, or (2)
arrange to deprive yourself of the benefit of the patent license for this
particular work, or (3) arrange, in a manner consistent with the
requirements of this License, to extend the patent license to downstream
recipients. “Knowingly relying” means you have actual knowledge that, but
for the patent license, your conveying the covered work in a country, or
your recipient's use of the covered work in a country, would infringe
one or more identifiable patents in that country that you have reason
to believe are valid.

If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties receiving
the covered work authorizing them to use, propagate, modify or convey a
specific copy of the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work and works
based on it.

A patent license is “discriminatory” if it does not include within the
scope of its coverage, prohibits the exercise of, or is conditioned on
the non-exercise of one or more of the rights that are specifically
granted under this License. You may not convey a covered work if you are
a party to an arrangement with a third party that is in the business of
distributing software, under which you make payment to the third party
based on the extent of your activity of conveying the work, and under
which the third party grants, to any of the parties who would receive the
covered work from you, a discriminatory patent license (a) in connection
with copies of the covered work conveyed by you (or copies made from
those copies), or (b) primarily for and in connection with specific
products or compilations that contain the covered work, unless you
entered into that arrangement, or that patent license was granted, prior
to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any
implied license or other defenses to infringement that may otherwise be
available to you under applicable patent law.

12. No Surrender of Others' Freedom.

If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot use,
propagate or convey a covered work so as to satisfy simultaneously your
obligations under this License and any other pertinent obligations, then
as a consequence you may not use, propagate or convey it at all. For
example, if you agree to terms that obligate you to collect a royalty for
further conveying from those to whom you convey the Program, the only way
you could satisfy both those terms and this License would be to refrain
entirely from conveying the Program.

13. Offering the Program as a Service.

If you make the functionality of the Program or a modified version
available to third parties as a service, you must make the Service Source
Code available via network download to everyone at no charge, under the
terms of this License. Making the functionality of the Program or
modified version available to third parties as a service includes,
without limitation, enabling third parties to interact with the
functionality of the Program or modified version remotely through a
computer network, offering a service the value of which entirely or
primarily derives from the value of the Program or modified version, or
offering a service that accomplishes for users the primary purpose of the
Program or modified version.

“Service Source Code” means the Corresponding Source for the Program or
the modified version, and the Corresponding Source for all programs that
you use to make the Program or modified version available as a service,
including, without limitation, management software, user interfaces,
application program interfaces, automation software, monitoring software,
backup software, storage software and hosting software, all such that a
user could run an instance of the service using the Service Source Code
you make available.

14. Revised Versions of this License.

MongoDB, Inc. may publish revised and/or new versions of the Server Side
Public License from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to address new
problems or concerns.

Each version is given a distinguishing version number. If the Program
specifies that a certain numbered version of the Server Side Public
License “or any later version” applies to it, you have the option of
following the terms and conditions either of that numbered version or of
any later version published by MongoDB, Inc. If the Program does not
specify a version number of the Server Side Public License, you may
choose any version ever published by MongoDB, Inc.

If the Program specifies that a proxy can decide which future versions of
the Server Side Public License can be used, that proxy's public statement
of acceptance of a version permanently authorizes you to choose that
version for the Program.

Later license versions may give you additional or different permissions.
However, no additional obligations are imposed on any author or copyright holder
as a result of your choosing to follow a later version.

15. Disclaimer of Warranty.

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

16. Limitation of Liability.

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF
THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO
LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

17. Interpretation of Sections 15 and 16.

If the disclaimer of warranty and limitation of liability provided above
cannot be given local legal effect according to their terms, reviewing
courts shall apply local law that most closely approximates an absolute
waiver of all civil liability in connection with the Program, unless a
warranty or assumption of liability accompanies a copy of the Program in
return for a fee.

                      END OF TERMS AND CONDITIONS
