Open Microscopy Environment

Hi Josh and others!

I tried using the Search API to find items which are linked to an annotation. I wanted to use either the ID or the namespace of the example annotation to restrict the result, but neither worked. Is this expected?

Here's an example how I perform the search:

Code: Select all

# this is contetn of the ScreenAcquisitionAnnotationLink table:
omero4_1=> select id, parent, child from ScreenAcquisitionAnnotationLink;
id | parent | child
----+--------+-------
  1 |     51 |   121
  2 |     51 |   125

an= FileAnnotationI()
an.ns = rstring('some.namesspace')
search.onlyType("ScreenAcquisition")
s.byAnnotatedWith((an,))
len(s.results())
>>> 2
an.ns = rstring('foo')
s.byAnnotatedWith((an,))
len(s.results())
>>> 2
an.ns = None
an.id = rlong(121)
s.byAnnotatedWith((an,))
len(s.results())
>>> 2


Thanks for help! Bernhard

Hi Bernhard,

byAnnotatedWith only takes the "main content" (which is badly explained in the Javadoc) -- i.e. textValue, booleanValue, doubleValue, file -- and the type of the annotation into account (no id, no ns). The implementation is provided by ome.services.search.AnnotatedWith which is a bit clearer. Support for namespaces via byAnnotatedWith would be a part of ticket:976.

Cheers,
