This chapter lists all the sources of data provided by Debtags. The formats of all this data sources is documented in the Data formats chapter.

Tag sources

This section contains a list of ways to get tag information for packages.

Packages file

The Packages file contains Tag: fields with tag information for every package.

Alioth database, reviewed

The data that end up in the Packages file can also be found at svn://svn.debian.org/debtags/tagdb/tags; it is the data coming from the Alioth database, after manual review.

Alioth unrevised

The data contributed, either via the web interface or e-mail submissions, is collected in a database on Alioth.

These data, which have not yet undergone manual reviewing, can be accessed at http://debtags.alioth.debian.org/tags/tags-current.gz.

Iterating.org

Iterating, a wiki-based software guide, are providing a tag database with their ranking information at http://www.iterating.com/tags/tags-current.gz.

This can be merged with the other tag data by adding "tags http://www.iterating.org/tags" as a tag source in /etc/debtags/sources.list and running debtags update.

Local merged tag information

debtags update generates merged tag database that includes all the tag data from all the tag sources configured in /etc/debtags/sources.list.

It can be found in /var/lib/debtags/package-tags, and it has an accompanying index for fast access in /var/lib/debtags/package-tags.idx and /var/lib/debtags/pkgidx.idx.

Vocabulary sources

The Debtags vocabulary, that describes the facets and tags available for use in Debtags, can be obtained from subversion at svn://svn.debian.org/debtags/vocabulary/trunk/debian-packages or via web at http://debtags.alioth.debian.org/tags/vocabulary.gz.

A copy of the vocabulary is also included in the Debtags package to support the tags provided with the Packages file. It can be found in /usr/share/debtags/vocabulary.

Finally, debtags update generates a merged vocabulary that includes all the vocabulary data from all the tag sources configured in /etc/debtags/sources.list. It can be found in /var/lib/debtags/vocabulary, and it has an accompanying index for fast access in /var/lib/debtags/vocabulary.idx.
