I appreciate this and admire the thought that went into it.
I wonder whether we shouldn't explicitly separate the concept of a "feature on
a genome" from "a biological object?" I keep bumping into this issue over
and over again, where people get stuck on the confusion between these three
a) a generic class of feature, such as "SINE repeat element"
b) a specific feature, such as "this H. sapiens ALU element consensus"
c) the position of the feature on the genome, such as "the ALU element
match that is right here"
By separating these concepts out, a DAS feature would then distinguish:
- an LSID that indicates the feature's Sequence Ontology type (a)
- an LSID that provides access to the rich biological description of
this object (b)
- an LSID that refers to a particular instance of this object on a genome (c)
I imagine that "the biological context" that you refer to in the proposal is
type (b). There should be a query interface for these objects and a way to
retrieve them that is distinct from the process of querying a feature by its
location and type that is provided by baseline DAS.
