Bruce Beckwith moderated discussion of the recent work in DICOM on a
pathology image standard.  There was general agreement that the LDIP
effort and the DICOM effort will be complementary, with the DICOM
effort providing image-specific elements that fit into the DICOM
structured format, and the LDIP effort providing a defined RDF
namespace, with classes and properties for data elements (i.e., an RDF
ontology).  There was agreement that LDIP will stay informed of the
DICOM work and include element tags corresponding to DICOM elements. 
Bruce will serve as liaison to ensure that the work of the two groups
is somewhat coordinated.  
Some of the limitations of RDF were discussed, particularly in regards
to enumerations for complex data types.  DAML is an RDF extension that
provdies enumerators for complex data types, and I sent around some
information on DAML immediately following the conference call.  
We concluded that we needed to see and discuss the DICOM elements and
that we would continue discussing ontology issues.  
Ilya Goldberg's question (from the prior conference call) about how we
should deal with the actual binary image data was tabled because Ilya
wasn't in attendance.  Immediately following the conference call, Ole
Eichhorn, Kemp Watson and Bob Leif had an in interesting exchange of
emails on the topic of embedded binaries.  Basically, the issue of
embedding LDIP metadata into the header of a commonly used image file
format keeps coming up, and we need to discuss this at some time.
