DAS1.6

Note: this is NOT the official version of the DAS specification.

Distributed Sequence 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:

• Draft 1
• Draft 2
• Draft 3
• Draft 3
