|Title: ||Metadata Extraction and Search Interfaces - Specification|
|Authors: ||Demidova, Elena|
|Issue Date: ||19-Nov-2007|
|Abstract: ||The Metadata Extraction and Search Interfaces offer a framework which allows for crawling
specific knowledge resources and extraction their metadata. Furthermore, extracted metadata
can be made persistently available for search using Metadata Extraction Listener and Search
Interfaces of the Framework. RDF description produced by the Metadata Extraction can be
adjusted using Ontology Mapper Interface.
The Metadata Extraction Interface can be used in two different ways. On the one hand it
provides methods to crawl a specified URI and mapping the metadata schema of the crawler
to the application ontology. The application has to take care about storing the returned
metadata. Alternatively, Metadata Extraction Interface provides listener/event based methods.
Thereby an application can be registered as a listener by the Metadata Extractor, which fires
an event to the listener providing the crawled metadata for each document. The listener then
has to take care about further processing like e.g. storing metadata.|
