Folks,    (09)

I'm not sure how this "[ontology-summit][Repository-Arch] Minimum
metadata for OOR" thread on the ontology-summit forum is meant to
with the OOR-Forum, so I will post this message to both. I was planning
post a message like the following to the OOR-Forum only until I saw this
thread on ontology-summit. Sorry to those of you who get this message
twice.    (010)

I think that there is some good input available for the subject of this
thread. A lot of time has been spent thinking about and modeling
metadata for "metadata registries" by participants of the eXtended
Registry (XMDR) project and related efforts in ISO/IEC JTC 1/SC 32/WG 2
INCITS L8 in the US). In development work for ISO/IEC 11179 Edition 3,
are extending metadata registries--previously focused on data elements &
classification systems--to improve registration of concept systems
(thesauri, taxonomies, ontologies, etc). There is particular attention
how semantics in concept systems relate to semantics in metadata and to
semantics in data. The XMDR project also developed a modular
for the XMDR prototype metadata registry (prototype of ISO/IEC 11179
3). The work should at least be useful to this effort. Here are some
links:    (011)

Architecture:    (012)

Here is a link to a software architecture page for the XMDR prototype.
was written quite some time ago, but has stood up pretty well:
http://www.xmdr.org/arch.html    (013)

I have attached an updated version of the architecture. It is a slide
from a
presentation that I recently presented during an OOR panel discussion.
that there are many possible software selections for each module in the
architecture; some of these are named on the web site. In the XMDR
prototype, we used all open source software, but commercial software
be substituted for reasons of functionality or performance.    (014)

Metadata for OOR:    (015)

I think that much of the minimum metadata for an OOR has been
Here are the latest UML figures proposed for the Edition 3 of ISO/IEC
These are the result of some mixture of proposals from XMDR and comments
made by SC 32/WG 2 (including INCITS L8) participants.    (016)

https://xmdr.lbl.gov/mediawiki/index.php/Latest_Diagrams    (017)

Diagrams of particular interest, might be:
1 Package Dependencies -- shows the major metadata modules
3.2 Registration metamodel region 
3.3 Concept System metamodel region 
3.4 Designation and Definition metamodel region 
3.6 Ontology metamodel region 
3.10 Classification metamodel region 
3.12 Relations metamodel region     (018)

Work is currently underway to consolidate four of the figures:
Classification, Concept System, 
Ontology, and Relations. Hopefully, this will make a good overview (if
replacement of) the four figures, which are a bit difficult.    (019)

The above figures are still being discussed and refined. Several of the
other figures on the "Latest Diagrams" page are more stable, some mostly
derived from Edition 2 of 11179.    (020)

Text for the figures is under development. A version of the text is
available in the document for Committee Draft 1 of ISO/IEC 11179 Part 3
(Edition 3), which was balloted in the fall of 2007. A few hundred
were received on that ballot and a lot of editing is being done. To get
look at an old version of the text, see:
8-15.doc    (021)

Note that for development of the XMDR prototype, the UML model figures
(ISO/IEC 11179-3 (E3)) were translated into an ontology as the basis for
implementation. I hope that the figures on the "Latest Figures" page
will be
translated into a new version of the ontology.    (022)

I think that the above gives more than the "minimum" required metadata.
minimum might be approximated by leaving out some of what is specified
the UML model. The figures may lack some metadata that we would like for
OOR, so we may need to add something. However, I think the above are
input to the discussion.    (023)
