Terminology Services

Goal

The goal of this project is to offer accessible, modular, web-based terminology services.

Project description

Web services are modular, web-based, machine-to-machine applications that can be combined in various ways. Web services can be accessed at various points in the metadata lifecycle, for example, when a work is authored or created, at the time an object is indexed or cataloged, or during search and retrieval. Terminology services are web services involving various types of knowledge organization resources, including authority files, subject heading systems, thesauri, web taxonomies, and classification schemes. A web service that provides mappings from a term in one vocabulary to one or more terms in another vocabulary is an example of a terminology service.

This project extends the capabilities for enhancing and mapping vocabularies developed under the terminology services sub-project of the Metadata Switch. Mappings have been made for the knowledge organization resources shown in the table below. Direct mappings are associations between equivalent terms in different controlled vocabularies or between verbal terms (e.g., subject headings) and classification numbers. Co-occurrence mappings are associations based on the co-occurrence of terms from different schemes in the same metadata or catalog record. Co-occurrence mappings are considered to be more loosely mapped than direct mappings, which usually have an intellectual review component.
