WebDAV
Although the WebDAV implementation we are going to use is provided by
Apache and could have been included in the list above, it is listed separately
because it is not required for core functionality; but we are going to use it to provide
additional features for our solution that we do not get with a straight Trac and
Subversion combo.
WebDAV is an abbreviation of Web-based Distributed Authoring and Versioning,
which refers to both an IETF working group and the set of extensions to the HTTP
protocol that the group defined, which allows users to collaboratively edit and
manage files on remote web servers. Its aim is to provide the functionality to create
and manage documents on a web server. The obvious use for this is for authoring
and publishing the documents that a web server serves, but it can also be utilized
for general web-based file storage that is accessible from anywhere. Support for
WebDAV is provided by most modern operating systems, and with the right client
and a fast network it can be almost as easy to use files on a WebDAV server as those
stored in local directories.
Our use for WebDAV is to:
Provide access to 'publish' releases and supporting files for download
Provide controlled access to non-wiki documents
Provide a publishing mechanism for images to be included in wiki pages
without using attachments
Since we are already using Apache to provide authentication for Trac and
Subversion, we can extend that to provide access control to our WebDAV files
as well.
