DAS1.6
Note: this is NOT the official version of the DAS specification.
Distributed Annotation System (DAS) 1.6
This is a working document and a proposal for a reworked DAS specification which hopes to:
- clarify the existing DAS spec
- better reflect how DAS is being used in the community today
- better reflect the use of DAS beyond the genome-centric arena (protein sequences and structures)
- ratify commands from the 1.53E spec
- introduce some ideas inspired by DAS/2
- formally introduce the DAS registry
- migrate from the use of DTDs for describing the XML formats to RelaxNG
Note: the DAS specification is a technical document but with some effort should hopefully be readable and understandable by people without a deep understanding of broader technical issues and other system architectures. That is, it makes only basic assumptions.
The specification has been written as a number of drafts:

(DAS) 1.6 Development and Tutorials
Dazzle Example adaptor for 1.6 spec source compliant with the registry
Subversion develpment repository http://www.derkholm.net/svn/repos/dazzle/branches/16Dazzle See class org.biojava.servlets.dazzle.datasource.SimpleFile16ExampleSource for a datasource that conforms to the new 1.6 Spec.
<datasource id="test16genes" jclass="org.biojava.servlets.dazzle.datasource">
<string name="name" value="16 File Test" />
<string name="description" value="Data source for testing 1.6 heirachy structure" />
<string name="version" value="1.0" />
<string name="fileName" value="test16genes.txt" />
<string name="stylesheet" value="test16.style" />
</datasource>
The new Dazzle implements the single Data Source sources.xml request: blah/das/myDataSourceName. The current implementation relies on on a valid sources.xml document being available and then parses the appropriate section from this document in response to a request.
The das registry also now responds to these requests e.g. http://www.dasregistry.org/das/DS_109
