17.2.2 Cross-Community Work
fl
ow for Agricultural
Metadata Aggregation
The presented use-case and example is intended to show how to integrate distrib-
uted computing infrastructure (for data processing and storing purposes) together
with metadata stores (registered in CIARD RING) containing bibliographical and
educational materials to achieve an interoperable cross-community platform for
agricultural web portals. One of the major tasks addressed was to enable transparent
search and browse in different metadata stores using completely different metadata
schemas. One other task concerning the differences among metadata stores was to
solve feeding them with new metadata records interactively (involving the users).
This latter case is called the harvesting process, and it contains methods (i) to fetch
all the records belonging to the repository, (ii) to index them based on vocabularies
in order (iii) to facilitate the further searches and
filtering methods, and (iv) to
eliminate all the duplicated records. This complex process has been implemented as
a gUSE workflow, and the involved components during this process are shown in
Fig.

.
CIARD RING consists of several repositories of metadata that store records in
various
fields of agriculture. As all the partner companies (e.g., AgroKnow) or
