The following charter applies to all Xalan projects.

1.1 Apache Xalan is a collaborative software development project dedicated to providing robust, full-featured, commercial-quality, and freely available XSLT support on a wide variety of platforms. This project is managed in cooperation with various individuals worldwide (both independent and company-affiliated experts), who use the Internet to communicate, plan, and develop XSLT software and related documentation.

1.2 This charter briefly describes the mission, history, organization and processes of the project.

2.1 Apache Xalan exists to promote the use of XSLT. We view XSLT (Extensible Stylesheet Language Transformations) as a compelling paradigm that transforms XML documents, thereby facilitating the exchange, transformation, and presentation of knowledge. The ability to transform XML documents into usable information has great potential to improve the functionality and use of information systems. We intend to build freely available XSLT processing components in order to engender such improvements.

2.2 Apache Xalan consists of a set of components that transform XML documents. Where appropriate, these components plug into other XML components using standard APIs (formal, de facto, or proposed). The components must be high performance, reliable, and easy to use. Where inter-related, the components must be part of an underlying architectural orchestration that will allow them to work together without major negotiations or breakage.

2.3 We believe that the best way to define this XML transformation architecture is by having both individuals and corporations collaborate on the best possible infrastructure, APIs, code, testing, and release cycles. Components must be vendor neutral and usable as core components for all.

2.4 In order to achieve a coherent architecture between Apache Xalan components and other components and applications, standards (formal or de facto) will be used as much as possible for both protocols and APIs. Where appropriate, experiences and lessons learned will be fed back to standards bodies in an effort to assist in the development of those standards. We will also encourage the innovation of new protocols, APIs, and components in order to seed new concepts not yet defined by standards.

3.1 This project was established under the direction of the Apache Software Foundation in October 2004 to facilitate joint open-source development. Prior to October 2004 this project was a subproject of the Apache XML project.

4.1 The ASF Board. The management board of the Apache Software Foundation.

4.2 The Project. The Apache Xalan project; intended to refer to the source code, website, subprojects, and community that are Apache Xalan.

4.3 Subproject. The Apache Xalan project may have subprojects; a subproject is responsible for a component or application whose scope is well defined.

4.4 Product. Some deliverable (usually a binary or source package) that a subproject makes available to the public. Subprojects may have multiple products.

4.5 Release. A specific version of a product. Subprojects may have multiple releases of a given product.

4.6 Contributor. Anyone who makes a contribution to the development of the Apache Xalan project.

4.7 Committer. The Apache Xalan project has a set of committers. Committers are contributors who have read/write access to the source code repository.

4.8 PMC. The PMC (Project Management Committee) is the group of people that form the entity that makes decisions and controls the project. Individual people or committers do not control the project.

5.1 The Apache Xalan project is managed by a core group of committers known as the Project Management Committee [PMC]. Subprojects, if any, much each have at least one representative committer on the PMC.

5.2 The activities of the PMC are coordinated by the Chairperson, who is an officer of the corporation and reports to the Apache Board. The Chairperson will, on the request of the Apache Board, provide reports to the Board on issues related to the running of the Apache Xalan project.

5.3 The PMC has the following responsibilities:

a) Accepting new subproject proposals, formally submitting these proposals for Apache Xalan committer vote, and creating the subproject (see SUBPROJECTS below). This is done in collaboration with the Incubator (see http://incubator.apache.org).

b) Facilitating code or other donations by individuals or companies, in collaboration with the Incubator.

c) Resolving license issues and other legal issues in conjunction with the ASF board.

d) Ensuring that administrative and infrastructure work is completed.

e) Facilitating relationships among projects and subprojects.

f) Facilitating relationships between the Apache Xalan project and the external world.

g) Overseeing Apache Xalan to ensure that the mission defined in this document is being fulfilled.

h) Resolving conflicts within the project.

i) Reporting to the ASF board (through the Chair) on the progress of the project.

j) Propose new releases of projects or subprojects. Such proposals pass if 75% of the PMC members vote in agreement.

5.4 A contributor can, at any time, nominate a committer to be on the PMC, by calling for a vote. If two thirds, or more, of the active committers vote in agreement then the nomination is given to the PMC. The person becomes a new PMC member if 75% or more of the PMC members vote in agreement, with no dissenting votes among the PMC members. This individual should be elected based on merit for the evolution of the project and demonstration of commitment.

5.5 In cases where the subproject is unable to directly provide a representative on the PMC, another member of the PMC will be required to represent that subproject on the PMC. This will be strongly discouraged. It is preferable that all subprojects have direct representation on the PMC.

5.6 At least every twelve months, or more often if directed by the ASF board, the PMC members will elect a Chairperson from among themselves; the person with the most votes from the other PMC members is recommended to the ASF board for the position of Chairperson, and with the ASF board's approval, becomes the Chairperson for the new term.

5.7 Upon agreement by the Apache Board, the recommended Chairperson will, if they are not already, be appointed an officer of the corporation. See http://www.apache.org/foundation/bylaws.html for more information.

5.8 The PMC is responsible for maintaining and updating this charter. Development must follow the process outlined below, so any change to the development process necessitates a change to the charter. Proposed changes to this charter by the PMC are passed if 75% or more of the PMC members approve the proposal, with no dissenting votes. However, an active Apache Xalan committer may challenge the change.

5.9 An active Apache Xalan committer may challenge a change to this charter proposed by the PMC within two weeks of its proposal. When challenged the proposed change is passed if within two weeks of the challenge the active committers approve the change with a two-thirds majority vote.

5.10 The PMC ultimately makes the decisions for the project, not the individual people. At any time the PMC can reject patches or other contributions to the project if 75% or more of the PMC members vote to reject the contribution.

5.11 A PMC member may resign their membership at any time. However, in the unlikely event that a member of the PMC becomes disruptive to the process, such as ceasing to take part in PMC votes, the PMC member may be removed from the PMC by a vote among the other PMC members. The PMC member is removed if 75% or more of the other PMC members approve the removal, with no dissenting votes among the other PMC members.

5.12 A person remains a PMC member until he or she resigns, is removed by a vote from among the other PMC members, dies or is incapacitated.

6.1 A subproject of the Apache Xalan project is responsible for a component or application whose scope is well defined. Each subproject has its own set of developers, and is responsible for approving its own committers. Apache Xalan is composed of subprojects which fit into one of two categories:

(a) An XSLT processor implementation in some particular programming language. There may be multiple processors for a given language if the API's the processors support are sufficiently dissimilar. At the time of writing, there is one processor for C++ and two for Java.

(b) A set of components which are used in related applications and are tightly bound, usually through internal API's, to one (or more) of the processor subprojects.

6.2 A new subproject proposal is submitted to the PMC, and then accepted by a majority Apache Xalan project active committer vote within two weeks after the proposal.

6.3 Each subproject must have a set of requirements as well as an up-to-date release plan and design document on its dedicated web page.

6.4 It is recommended that each subproject have a smoke-test system that works at least as a basic integration test.

6.5 A subproject may be removed if 75% or more of the PMC members approve the proposal, there are no dissenting votes among the PMC members, and no challenges by active Apache Xalan project committers within two weeks after the proposal. A contributor may challenge the proposed removal of a subproject within two weeks of the proposal. In this case the proposed removal is passed if within two weeks of the challenge the active committers approve the removal with a two-thirds majority vote. Any subproject removal is subject to the approval of the ASF board.

7.1 Like all Apache projects, the Apache Xalan project is a meritocracy -- the more work you do, the more you are allowed to do.

7.2 People who make regular and substantial contributions may become committers as described below. Contributions include: participating in mailing lists, reporting issues or bugs in issue-records in the Issue Database, providing patches, and proposing changes to a product.

7.3 In order to ensure that all code contained in the Apache Xalan project's code repository is free of licensing, intellectual property and patent issues, any person wishing to contribute a new feature to Apache Xalan must either sign:

a) If contributing as an individual, sign the "Individual Contributor License Agreement (CLA)" (http://www.apache.org/licenses/icla.txt) and file a copy with the Secretary of the Corporation; or

b) If making the contribution as part of their employment responsibilities, sign the "Corporate CLA (CCLA)", (http://www.apache.org/licenses/cla-corporate.txt) and file a copy with the Secretary of the Corporation.

7.4 If the contribution in question is a small bugfix, the contributor need not sign a CLA, but need only provide the following information, attaching it to the communication containing the patch:

a) Name and employer

b) Are you the author of the code being contributed?

c) Do you have the right to grant the copyright and patent licenses for the contribution that are set forth in the ASF v.2.0 license (http://www.apache.org/licenses/LICENSE-2.0)?

d) Does your employer have any rights to code that you have written, for example, through your contract for employment? If so, has your employer given you permission to contribute the code on its behalf or waived its rights in the code?

e) Are you aware of any third-party licenses or other restrictions (such as related patents or trademarks) that could apply to your contribution? If so, what are they?

8.1 The Apache Xalan project has a set of committers. If there are subprojects, each subproject will also have a set of committers. Committers are contributors who have read/write access to the source code repository. New committers are added when a contributor is nominated by a committer and approved by at least 50 percent of the active committers for that subproject with no opposing votes. In most cases, new committers will already be participating in the development process by submitting suggestions and/or fixes via issue-records in the Issue Database or mailing lists.

8.2 For the purposes of voting, committers will be classed as "active" or "inactive". Only active committers will be included in the totals used to determine the success or failure of a particular vote.

8.3 Committers remain active as long as they are contributing code or posting to the project or subproject mailing lists. If a committers has neither contributed code nor posted to the mailing lists in 3 months, a member of the PMC will e-mail the committer, the project or subproject development list, and the PMC mailing list notifying the committer that they are now in inactive status.

8.4 An inactive status will not prevent a committer committing new code changes or posting to the mailing lists. Either of these activities will automatically re-activate the committer for the purposes of voting.

9.1 The Apache Xalan project relies on the Apache XML project and the Apache Infrastructure project for the following:

a) Issue Database -- This is a system with issue-records, for tracking bugs, issues, features and requests.

b) Repository -- The xalan.apache.org project has its set of parts that make up the software, and these parts are managed in a repository. Committers make changes to the source code, documentation and other associated parts that are stored in the repository. Any subproject will have its set of committers for its repository.

c) Website -- The website xalan.apache.org will contain information about the Apache Xalan project and its subprojects, including documentation, downloads of releases, and this charter.

d) Mailing Lists -- appropriate mailing lists will be created at the discretion of the PMC. Such mailing lists could for example include: a PMC mailing list, a general mailing list, project or subproject public developer mailing lists, project or subproject public user mailing lists.

10.1 All contributions to the Apache Xalan project adhere to the "Apache Software Foundation License, Version 2.0" (http://www.apache.org/licenses/LICENSE-2.0). All further contributions, including patches, must be made under the same terms.

10.2 When a committer is considering integrating a contribution from a contributor who has no CLA on file with the Corporation, it is the responsibility of the committer, in consultation with the PMC, to conduct due diligence on the pedigree of the contribution under consideration; see sections 7.3 and 7.4.

11.1 For a committer to commit a change to the MAIN branch of the repository an issue-record must be opened in the "Issue Database" to track the change. The status of the issue must be kept up to date.

11.2 No voting is required to commit changes, but one other active committer must review the changes. Before the changes are committed, the reviewer must add a comment in the corresponding issue-record indicating that they have reviewed and approve the changes.

11.3 Issue-records and reviews are not required for committing changes to other experimental branches (not the MAIN branch) in a repository.

12.1 Unless otherwise stated in this mission, votes cast on Apache Xalan proposals must be made within two weeks of the proposal. A challenge to a proposal must also be made within two weeks of the proposal. Likewise, votes cast on challenges must be cast within two weeks of the challenge.

13.1 The Apache Xalan project should work closely with other Apache projects, such as Xerces and XML, to avoid redundancy and achieve a coherent architecture among Apache Xalan and these projects.
