[Kim-discussion] Issue with getEntites method in CoreDBApi

[alistair.duke at bt.com]

Hi Danko,
 
Thanks for the speedy reply.
 
The scenario is as follows. I'm running a query which specifies
constraints based on structured metadata associated with the documents
(this metadata is held outside of KIM in a simple database table). This
results in a set of documents which satisfy the query. Since I
associated the KIM docIds with these documents at index time, I want to
send the resulting KIM docids to KIM to give me the top occuring
organisations, people, etc (rather like the default CORE interface) in
that result set. The getEntites query seemed like an ideal way to
achieve this in one step.
 
I suppose an alternative would be to use
 
ResultSetIterator
<file://../com/ontotext/kim/client/coredb/ResultSetIterator.html>
getEntities(Set
<http://java.sun.com/j2se/1.5.0/docs/api/java/util/Set.html>  docIds) 
 
to get all entities and then build some sort of filter to sort the
results into organisations, people, etc but this seems rather clunky in
comparison. Is there a better way?
 
Thanks,
 
Alistair

	Hi Alistar,
	 
	It happens so that from some time we do not support the:
	  getEntities(Set
<http://java.sun.com/j2se/1.5.0/docs/api/java/util/Set.html>  docIds,
CoreDbQuery
<file://\\..\com\ontotext\kim\client\coredb\query\CoreDbQuery.html>
query)
	version of the method. It just redirects the execution to:
	  getEntities(CoreDbQuery
<file://\\..\com\ontotext\kim\client\coredb\query\CoreDbQuery.html>
query)
	not to break old implementations.
	It was our oversight that we didn't remarked it in the
documentation.
	 
	But you can share the querying scenario you try to implements
and we will help with it.
	 
	Greetings,
	DanKo

		Hi again, 

		I've found some strange behaviour when using the
getEntities method of the CoreDbApi. If I use the 

		ResultSetIterator
<file://../../../../../com/ontotext/kim/client/coredb/ResultSetIterator.
html>  getEntities(Set
<http://java.sun.com/j2se/1.5.0/docs/api/java/util/Set.html>  docIds) 

		form it works fine i.e. I just get the entities in the
documents defined in the set. However, if I use the 

		ResultSetIterator
<file://../../../../../com/ontotext/kim/client/coredb/ResultSetIterator.
html>  getEntities(Set
<http://java.sun.com/j2se/1.5.0/docs/api/java/util/Set.html>  docIds,
CoreDbQuery
<file://../../../../../com/ontotext/kim/client/coredb/query/CoreDbQuery.
html>  query) 
		form, it only seems to look at the query restrictions
and ignores the docid restrictions. This means I get all entites
regardless of whether they are in the specified documents or not.

		I'm using KIM 2.5. Is this something you've come across?


		Thanks, 

		Alistair
