[Bioperl-l] Re: [BioSQL-l] namespace and find_by_unique_key

[Hilmar Lapp]

I made the following changes in bioperl-db:

	- be strict if namespace is provided with the query object (i.e., if 
it is provided and not found, you won't find the accession or 
identifier either).

	- allow namespace to be omitted from the query object for the query by 
identifier ($seq->primary_id)

	- namespace must be provided (and found) for a by-accession query to 
be successful

	- version# is optional for (accession,version,namespace) queries; if 
defined it will be used and otherwise will match whatever version is in 
the database. CAVEAT: if you have multiple versions of the same 
accession in the same namespace and you omit the version when querying 
by unique key, you'll get an exception because multiple rows will match.

Let me know any comments, suggestions, and feedback if this behavior is 
not useful.
