If I've omitted anyone, please let me know. 

The meeting started with a recap of the image workshop at APIII (Ul
Balis). Ul reported that there was much enthusiasm for the ldip
specification.  Bob Leif added that ISAC was also interested in the
specification.  Bruce Beckwith said that there was some discussion of
LDIP at the most recent DICOM meeting and, based on remarks, there is
a need to make the DICOM people understand that LDIP is intended to be
a complementary (not competitive) effort.  
We discussed the RDF draft/conversion of OME and the proposal that the
LDIP vocabulary be built as an RDF schema.  The LDIP.XML RDF schema
draft was emailed to the group prior to the conference call, and LDIP
members are urged to review the file and the covering email message.  
Problems discussed were: 

1. Size and complexity of the RDF schema due to many disparate data
elements  
2. Importance of having an xsd 

3. Limitations of RDF as a data specification 

General conclusions: 

1. RDF would be a good start for an LDIP namespace that will hold the
relationships between data elements  
2. Having elements described in RDF would facilitate the eventual
creation of an ldip xsd  
At the end of the conference call Ilya Goldberg brought up the issus
of how to encapsulate the binary image data (as an external file with
pointer, OR as an internal file in the image document, OR to simply
put all of the LDIP metadata into the header of a standard image file,
such as TIFF).  This discussion was stopped at 2:05 because we're
trying to keep conference calls to an hour to accommodate our
schedules.  However, we will carryover this discussion to the
listserver and will pick it up at the next conference call.  
The next conference call my need to be rescheduled because of a
conflict  in schedules for myself and Ul Balis.
