Bulgarian CHM - meta data management
I. About meta data. The successful development, operation
and use of complex informational system heavily depends on the effective
use and management of metadata. This metadata is needed for analysis,
system design, development, usage and solving interoperability problems.
Bulgarian CHM works intensively on the interoperability of our National
Clearing -House mechanism. One of the priorities is the metadata
development and management.
There are two levels of document description:
a) Semantics: This refers to agreements about content
description standarts. The DUBLIN CORE is the description standart adopted
by Bulgarian CHM. More information about the DUBLIN CORE can be found
on the Dublin Core Metadata Initiative web site - http://www.dublincore.org
b) Structure: Bulgarian CHM uses the Resource Description
Framework (RDF) model to specify semantic shemas so they can be shared.
Here is sample of .RDF files -
The portal web site -

II. Bulgarian CHM has meta data developed for:
1) Bulgarian CHM portal web site
2) Data base and web application dealing with books, articles, periodicals,
reports, volume editions, book series, publications and ÑD editions
in the field of Biodiversity.
III. We plan to develop meta databases for all structured
data in the Bulgarian CHM:
-
Data base and web application dealing with Specialists, Projects/Programs
and Institutions/Organizations in the field of biodiversity
-
Data base and web application dealing with books, articles, periodicals,
reports, volume editions, book series, publications and ÑD editions
in the field of Biodiversity - http://chm.moew.government.bg/searchMen.cfm
-
Data base and web application dealing with the National Forestry
Board, the Regional Forestry Boards, the State Forestries (SF) and
the State Game Breeding Stations (SGBS) - http://www.new.nug.bg/rug/rugen/
-
