Data concerning projects, people, organizations, members, and more is spread across multiple, separate data sources. This makes querying across data challenging. In some cases, data is replicated from one database to another to facilitate some queries while providing an added layer of protection. The database that contains committer information, the so-called "Foundation" database, is kept separate from other systems to provide an added layer of protection against private data being compromised. Bits of that database are replicated into an "Eclipse" database for access from the public website.

Project management is essentially a document-management and workflow problem. Several solutions exist in this area.

Moved to [[Project Management Infrastructure/Technology Choices]].

The Eclipse Foundation currently uses Drupal for [http://markeplace.eclipse.org Eclipse Marketplace], [http://live.eclipse.org Eclipse Live], and the [http://www.eclipsecon.org EclipseCon Website]. Several Eclipse Foundation employees are already well-versed in Drupal development, and finding temporary resources with the necessary skills in the local area should be relatively easy and cost-effective. Drupal is based on PHP, a language that is known to most of the Eclipse Foundation staff, and is currently in wide deployment by the Eclipse Foundation.
+
 
+
Perhaps one of the features that weighs most heavily in Drupal's favour is the size of the community behind it (which measures in the hundreds of thousands) and the hundreds (perhaps thousands) of plugins that are available to extend it. The availability of plugins, combined with the relative ease with which Drupal can be extended means that the overall amount of custom code that needs to be maintained should be relatively small (as compared to other solutions that may require more customization).
+
 
+
There are several other options that have been considered, including a handful of Eclipse-based solutions (which would allow us to "eat our own dogfood"). After careful consideration, however, we have determined that we do not have the resources to implement these solutions.

The new system will use LDAP for user authentication and for some aspects of authorization. This implementation will be based on work being done in {{Bug|364605}} that intends to standardize the entire eclipse.org infrastructure on the LDAP (Bugzilla-based authentication is used for most eclipse.org properties; LDAP is currently only used for committer authentication).
+
  
LDAP groups are used for project-based authorization. Users who have committer access to a project are members of an LDAP group that corresponds to the project. This group membership is bound to Drupal authentication via Drupal "organic groups" functionality. Additional authorization schemes are required to handle PMC-access to projects and other corner cases. For more information, see {{Bug|363614}}.

* Everything is undoable (i.e. revision tracking); and
+
* Do the simplest thing that can possibly work (avoid complexity)
+
  
We assume that committers will always endeavour to do the right thing. Specifically, we give committers leeway to do what they think is right. This, in combination with revision tracking means that mistakes can be easily undone. A committer may, for example, make ill-informed changes to a project's scope that is later reversed by the project lead or PMC.

It would be easy to get mired in multiple layers of approvals for various activities, or complex logic to prevent committers from shooting themselves in the proverbial foot. But such complexity makes the cost of later change and ongoing maintenance prohibitively high.

Note that we make a distinction between committers and general users. We do not--as a general rule--trust the general population to do the right thing. For completeness, we include with the definition of "committers" all those users with roles that permit them access to the project (including project leads, pmc members, EMO staff, etc.)

This effort is being tracked by Bug 243223.

Note that this document is not intended to be all inclusive. The combination of this document, the existing Developer Portal Use Cases, and the Eclipse Development Process form a more complete picture.

Problem Statement

Current infrastructure (i.e. The Developer Portal) is inadequate.

Data concerning projects, people, organizations, members, and more is spread across multiple, separate data sources. This makes querying across data challenging. In some cases, data is replicated from one database to another to facilitate some queries while providing an added layer of protection. The database that contains committer information, the so-called "Foundation" database, is kept separate from other systems to provide an added layer of protection against private data being compromised. Bits of that database are replicated into an "Eclipse" database for access from the public website.

Portal is separate from the the resources being managed; this requires a context switch to use. The content displayed in the project summary pages, for example, comes from the portal. When a committer notices that the data in the project summary is incorrect, they must switch into the portal to make the change. Most committers have difficulty (or outright refuse) to make that context switch.

Some management tasks are spread out. Specifying a description for a project, for example, requires that an HTML file be created in the project directory (requires CVS check-in), and then the specification of a URL in the portal. This is very difficult to maintain as it is separated from where and how the description is used, and requires multiple steps with multiple tools to complete. As a result, descriptions tend to be poorly specified, and rarely maintained.

Too much information is not included in or managed by the portal. Project proposals, review documentation, IP logs, are all separate.
