ArticleMigrating Bibliographic Datasets to the Semantic Web: the AGRIS case 2010
Also available in:
No results found.AGRIS is among the most comprehensive online collections of agricultural and related sciences information. It is a growing glob-al catalog of 5 million high-quality structured bibliographic records indexed from a worldwide group of providers. AGRIS relies heavily on the AGROVOC thesaurus for its indexing. Following the conversion of that thesaurus into a SKOS concept-scheme and its publication as Linked Open Data (LOD), the entire set of AGRIS records was also triplified and released as LOD. As part of this exercise, OpenAGRIS, a semantic mashup application, was developed to dynamically combine AGRIS data with external data sources, using a mixture of SPARQL queries and web services. The re-engineering of AGRIS for the Semantic Web raised numerous issues regarding the relative lack of administrative metadata required to compellingly address the proof and trust layers of the Semantic Web stack, both within the AGRIS repository and in the external data pulled into OpenAGRIS. The AGRIS te am began a process of disambiguation and enrichment to continue moving toward an entity-based view of its resources, beginning with the tens of thousands of journals attached to its records. The evolution of the system, the issues raised during the triplification process and the steps necessary for publishing the result as LOD content are hereby discussed and evaluated. -
Book (stand-alone)FAO's experience in metadata exchange from CDS/ISIS bibliographic databases using XML format, compliant to Dublin Core standard 2006
Also available in:
No results found.One of the problems in collaborative networks of documentation centers is the lack of interoperability between the different types of systems and applications used. The metadata is created in various places, time and using a number of tools and applications, data structures, content types, formats, and standards that may vary according to local needs. Exchange specifications that identify a minimum set of common requirements can be used for to facilitate the exchange and re-use of data. This p aper summarizes FAO’s experience in the efficient management and use of multilingual bibliographic CDS/ISIS databases, applying DC metadata standards and tools for search and exchange of bibliographic metadata. It explains in detail different approaches on how the bibliographic data from the CDS/ISIS databases can be converted and exported according to the Dublin Core (DC) and Agricultural Metadata Element Set (AgMES) based metadata set for cohesive and efficient platform-independent exchange of metadata. The second point is how different database applications can be united in a common search interface using DC elements. In addition, export features of DOS-, WINDOWS- and WEB-based CDS/ISIS application systems tools are compared. A number of examples on how the data in various input and storage formats can be reformatted without any modifications to the existing CDS/ISIS database and applications. The experience was gathered while working with FAO’s on-line library catalogue ( FAOBIB) and the International Information System for the Agricultural Sciences and Technology (AGRIS). The solution adopted was to use the Dublin Core (DC) and Agricultural Metadata Element Set (AgMES) based metadata set for the platform-independent exchange of metadata between existing databases. -
