PREAMBLE

Open Hardware is a thing - a physical artifact, either electrical or mechanical
- whose design information is available to, and usable by, the public in a way
that allows anyone to make, modify, distribute, and use that thing. In this
preface, design information is called "documentation" and things created from it
are called "products."

The TAPR Open Hardware License ("OHL") agreement provides a legal framework for
Open Hardware projects. It may be used for any kind of product, be it a hammer
or a computer motherboard, and is TAPR's contribution to the community; anyone
may use the OHL for their Open Hardware project.

Like the GNU General Public License, the OHL is designed to guarantee your
freedom to share and to create. It forbids anyone who receives rights under the
OHL to deny any other licensee those same rights to copy, modify, and distribute
documentation, and to make, use and distribute products based on that
documentation.

Unlike the GPL, the OHL is not primarily a copyright license. While copyright
protects documentation from unauthorized copying, modification, and
distribution, it has little to do with your right to make, distribute, or use a
product based on that documentation. For better or worse, patents play a
significant role in those activities. Although it does not prohibit anyone from
patenting inventions embodied in an Open Hardware design, and of course cannot
prevent a third party from enforcing their patent rights, those who benefit from
an OHL design may not bring lawsuits claiming that design infringes their
patents or other intellectual property.

The OHL addresses unique issues involved in the creation of tangible, physical
things, but does not cover software, firmware, or code loaded into programmable
devices. A copyright-oriented license such as the GPL better suits these
creations.

How can you use the OHL, or a design based upon it? While the terms and
conditions below take precedence over this preamble, here is a summary:

   *
   You may modify the documentation and make products based upon it.

   *
   You may use products for any legal purpose without limitation.

   *
   You may distribute unmodified documentation, but you must include the
   complete package as you received it.

   *
   You may distribute products you make to third parties, if you either include
   the documentation on which the product is based, or make it available without
   charge for at least three years to anyone who requests it.

   *
   You may distribute modified documentation or products based on it, if you:

      *
      License your modifications under the OHL.

      *
      Include those modifications, following the requirements stated below.

      *
      Attempt to send the modified documentation by email to any of the
      developers who have provided their email address. This is a good faith
      obligation - if the email fails, you need do nothing more and may go on
      with your distribution.

   *
   If you create a design that you want to license under the OHL, you should:

      *
      Include this document in a file named LICENSE (with the appropriate
      extension) that is included in the documentation package.

      *
      If the file format allows, include a notice like "Licensed under the TAPR
      Open Hardware License (www.tapr.org/OHL)" in each documentation file.
      While not required, you should also include this notice on printed circuit
      board artwork and the product itself; if space is limited the notice can
      be shortened or abbreviated.

      *
      Include a copyright notice in each file and on printed circuit board
      artwork.

      *
      If you wish to be notified of modifications that others may make, include
      your email address in a file named "CONTRIB.TXT" or something similar.

   *
   Any time the OHL requires you to make documentation available to others, you
   must include all the materials you received from the upstream licensors. In
   addition, if you have modified the documentation:

      *
      You must identify the modifications in a text file (preferably named
      "CHANGES.TXT") that you include with the documentation. That file must
      also include a statement like "These modifications are licensed under the
      TAPR Open Hardware License."

      *
      You must include any new files you created, including any manufacturing
      files (such as Gerber files) you create in the course of making products.

      *
      You must include both "before" and "after" versions of all files you
      modified.

      *
      You may include files in proprietary formats, but you must also include
      open format versions (such as Gerber, ASCII, Postscript, or PDF) if your
      tools can create them.

TERMS AND CONDITIONS

1. Introduction

   (( 1.1 ))??
   This Agreement governs how you may use, copy, modify, and distribute
   Documentation, and how you may make, have made, and distribute Products based
   on that Documentation. As used in this Agreement, to "distribute"
   Documentation means to directly or indirectly make copies available to a
   third party, and to "distribute" Products means to directly or indirectly
   give, loan, sell or otherwise transfer them to a third party.

   (( 1.2 ))??
   "Documentation" includes:

      (( (a) ))??
      schematic diagrams;

      (( (b) ))??
      circuit or circuit board layouts, including Gerber and other data files
      used for manufacture;

      (( c ))??
      mechanical drawings, including CAD, CAM, and other data files used for
      manufacture;

      (( (d) ))??
      flow charts and descriptive text; and

      (( (e) ))??
      other explanatory material.

   Documentation may be in any tangible or intangible form of expression,
   including but not limited to computer files in open or proprietary formats
   and representations on paper, film, or other media.

   (( 1.3 ))??
   "Products" include:

      (( (a) ))??
      circuit boards, mechanical assemblies, and other physical parts and
      components;

      (( (b) ))??
      assembled or partially assembled units (including components and
      subassemblies); and

      (( c ))??
      parts and components combined into kits intended for assembly by others;
      which are based in whole or in part on the Documentation.

   (( 1.4 ))??
   This Agreement applies to any Documentation which contains a notice stating
   it is subject to the TAPR Open Hardware License, and to all Products based in
   whole or in part on that Documentation. If Documentation is distributed in an
   archive (such as a "zip" file) which includes this document, all files in
   that archive are subject to this Agreement unless they are specifically
   excluded. Each person who contributes content to the Documentation is
   referred to in this Agreement as a "Licensor."

   (( 1.5 ))??
   By (a) using, copying, modifying, or distributing the Documentation, or (b)
   making or having Products made or distributing them, you accept this
   Agreement, agree to comply with its terms, and become a "Licensee." Any
   activity inconsistent with this Agreement will automatically terminate your
   rights under it (including the immunities from suit granted in Section 2),
   but the rights of others who have received Documentation, or have obtained
   Products, directly or indirectly from you will not be affected so long as
   they fully comply with it themselves.

   (( 1.6 ))??
   This Agreement does not apply to software, firmware, or code loaded into
   programmable devices which may be used in conjunction with Documentation or
   Products. Such software is subject to the license terms established by its
   copyright holder(s).

2. Patents

   (( 2.1 ))??
   Each Licensor grants you, every other Licensee, and every possessor or user
   of Products a perpetual, worldwide, and royalty-free immunity from suit under
   any patent, patent application, or other intellectual property right which he
   or she controls, to the extent necessary to make, have made, possess, use,
   and distribute Products. This immunity does not extend to infringement
   arising from modifications subsequently made by others.

   (( 2.2 ))??
   If you make or have Products made, or distribute Documentation that you have
   modified, you grant every Licensor, every other Licensee, and every possessor
   or user of Products a perpetual, worldwide, and royalty-free immunity from
   suit under any patent, patent application, or other intellectual property
   right which you control, to the extent necessary to make, have made, possess,
   use, and distribute Products. This immunity does not extend to infringement
   arising from modifications subsequently made by others.

   (( 2.3 ))??
   To avoid doubt, providing Documentation to a third party for the sole purpose
   of having that party make Products on your behalf is not considered
   "distribution,"\" and a third party's act of making Products solely on your
   behalf does not cause that party to grant the immunity described in the
   preceding paragraph.

   (( 2.4 ))??
   These grants of immunity are a material part of this Agreement, and form a
   portion of the consideration given by each party to the other. If any court
   judgment or legal agreement prevents you from granting the immunity required
   by this Section, your rights under this Agreement will terminate and you may
   no longer use, copy, modify or distribute the Documentation, or make, have
   made, or distribute Products.

3. Modifications

You may modify the Documentation, and those modifications will become part of
the Documentation. They are subject to this Agreement, as are Products based in
whole or in part on them. If you distribute the modified Documentation, or
Products based in whole or in part upon it, you must email the modified
Documentation in a form compliant with Section 4 to each Licensor who has
provided an email address with the Documentation. Attempting to send the email
completes your obligations under this Section and you need take no further
action if any address fails.

4. Distributing Documentation

   (( 4.1 ))??
   You may distribute unmodified copies of the Documentation in its entirety in
   any medium, provided that you retain all copyright and other notices
   (including references to this Agreement) included by each Licensor, and
   include an unaltered copy of this Agreement.

   (( 4.2 ))??
   You may distribute modified copies of the Documentation if you comply with
   all the requirements of the preceding paragraph and:

      (( (a) ))??
      include a prominent notice in an ASCII or other open format file
      identifying those elements of the Documentation that you changed, and
      stating that the modifications are licensed under the terms of this
      Agreement;

      (( (b) ))??
      include all new documentation files that you create, as well as both the
      original and modified versions of each file you change (files may be in
      your development tool's native file format, but if reasonably possible,
      you must also include open format, such as Gerber, ASCII, Postscript, or
      PDF, versions);

      (( c ))??
      do not change the terms of this Agreement with respect to subsequent
      licensees; and

      (( (d) ))??
      if you make or have Products made, include in the Documentation all
      elements reasonably required to permit others to make Products, including
      Gerber, CAD/CAM and other files used for manufacture.

5. Making Products

   (( 5.1 ))??
   You may use the Documentation to make or have Products made, provided that
   each Product retains any notices included by the Licensor (including, but not
   limited to, copyright notices on circuit boards).

   (( 5.2 ))??
   You may distribute Products you make or have made, provided that you include
   with each unit a copy of the Documentation in a form consistent with Section
   4. Alternatively, you may include either (i) an offer valid for at least
   three years to provide that Documentation, at no charge other than the
   reasonable cost of media and postage, to any person who requests it; or (ii)
   a URL where that Documentation may be downloaded, available for at least
   three years after you last distribute the Product.

6. NEW LICENSE VERSIONS

TAPR may publish updated versions of the OHL which retain the same general
provisions as the present version, but differ in detail to address new problems
or concerns, and carry a distinguishing version number. If the Documentation
specifies a version number which applies to it and "any later version", you may
choose either that version or any later version published by TAPR. If the
Documentation does not specify a version number, you may choose any version ever
published by TAPR. TAPR owns the copyright to the OHL, but grants permission to
any person to copy, distribute, and use it in unmodified form.

7. WARRANTY AND LIABILITY LIMITATIONS

   (( 7.1 ))??
   THE DOCUMENTATION IS PROVIDED ON AN"AS-IS" BASIS WITHOUT WARRANTY OF ANY
   KIND, TO THE EXTENT PERMITTED BY APPLICABLE LAW. ALL WARRANTIES, EXPRESS OR
   IMPLIED, INCLUDING BUT NOT LIMITED TO ANY WARRANTIES OF MERCHANTABILITY,
   FITNESS FOR A PARTICULAR PURPOSE, AND TITLE, ARE HEREBY EXPRESSLY
   DISCLAIMED.

   (( 7.2 ))??
   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ANY LICENSOR BE LIABLE TO
   YOU OR ANY THIRD PARTY FOR ANY DIRECT, INDIRECT, INCIDENTAL, CONSEQUENTIAL,
   PUNITIVE, OR EXEMPLARY DAMAGES ARISING OUT OF THE USE OF, OR INABILITY TO
   USE, THE DOCUMENTATION OR PRODUCTS, INCLUDING BUT NOT LIMITED TO CLAIMS OF
   INTELLECTUAL PROPERTY INFRINGEMENT OR LOSS OF DATA, EVEN IF THAT PARTY HAS
   BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

   (( 7.3 ))??
   You agree that the foregoing limitations are reasonable due to the
   non-financial nature of the transaction represented by this Agreement, and
   acknowledge that were it not for these limitations, the Licensor(s) would not
   be willing to make the Documentation available to you.

   (( 7.4 ))??
   You agree to defend, indemnify, and hold each Licensor harmless from any
   claim brought by a third party alleging any defect in the design,
   manufacture, or operation of any Product which you make, have made, or
   distribute pursuant to this Agreement.
