Dear all,
I believe we should first of all make clear what a conceptual model is
(_briefly_). We have to distinguish the role of conceptual model
vis-à-vis metadata schemas, content standards etc. For example, metadata
schemas are focusing description and on covering the search and
retrieval needs of users, whilst ontologies’ target is to specify the
semantic notions that define a domain (e.g. cultural heritage,
multimedia, legal etc.) and their interrelationships providing a wider
yet explicitly specified aspect, mostly oriented to cover information
integration needs (i.e. facilitates reasoning, higher degree of
abstraction, query model that corresponds to the users’ view of the
domain, integration, inter-ontology mappings).
Dear Lina,
We should be careful to compare comparable things. Unfortunately, the domain
is full of contradictory definitions.
I recommend as a discussion base:
Section 4.1.5 in:
"PATEL, M., KOCH, T., DOERR, M., TSINARAKI, C., GIOLDASIS, N., GOLUB, K., AND TUDHOPE, D. 2005. Semantic Interoperability in Digital Library
Systems, DELOS Network of Excellence on Digital Libraries – deliverable 5.3.1, June 2005."

To my understanding, "ontology" in general has no target other than any human
conceptualization.
An ontology can explicate the constructs of any metadata schema.
A "metadata schema" IsA normal schema with a particular relationship, which
does not affect its
substance in contrast to "conceptual model". It is a normal data schema "used"
to describe objects that happen to contain data.
This accidental relationship has no bearing on the fundamentals of its
substance.
It is on the same level as "office automation schema".
The CRM is an ontology particularly made to explain the underlying concepts of
metadata schemata
and other data schemata.
In the tendency to (ab)use the term "ontology" for everything that has to to
with data and knowledge, seems
also to have as an effect that information science seems slowly to adopt the
term as synonym of terminological
data (subject terms, classification systems etc.).
For CRM-SIG, I suggest to stay with Nicola Guarino's definition of ontology
basically saying (in my words):
a formal theory about possible states of affairs approximating a human
conceptualization.
Kind regards,
Martin

Subject: [Crm-sig] About the short document for the archive community
Here are some ideas for the short document for the archive community
(Friday 7th Nov. 9:30-):
The common ontology for museums, libraries and archives should enable
capturing information about curated artifacts in a way that takes into
account object, process and context:
(1) Object related information includes
- Descriptive information about the artifact itself
(2) Process related information includes information about
- Events and activities related to the creation of artifacts
- Events and activities related to the history of artifacts
- Events and activities related to the curation and storage of artifacts
(3) Context related information includes
- Information about context of creation and original use of the artifact
- Contextual information related to the history of the artifact
- Information about the contemporary context of the artifact
Best regards,
Mika
