Revision as of 12:58, 19 October 2010
Distributed Annotation System (DAS) 1.6
DAS 1.6 is, as of 19th October 2010, the latest official version of the DAS specification.
It is the first official version published in several years, and aims to:
- clarify ambiguities in the previous DAS specification
- 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
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 was developed via progression through a number of drafts:
