Authority linking

Personal name authorities and works (as of Muscat 5.0) are linked to the Virtual International Authority File (VIAF). A field in the cataloguing interface allows for searching VIAF directly from Muscat and selecting the corresponding entry. The mapping between the RISM authority entry and VIAF makes it possible to link further with other resources that use VIAF.

Work authorities

Muscat 5.0 has an authority file for works, which can link to the VIAF work authority entries. An authority record for a work records all information that is true for a work as a whole, no matter what other forms a piece of music exists in, whether it be—for example—an arrangement, a translation, a full score, or a single manuscript. Authority records can include the composer, title, title variants, key, instrumentation, and incipits. Associating a musical source in Muscat with an authority record for a work ensures that all instances of any given piece of music are linked together. This improves the searchability of the catalog and helps users find all relevant sources, regardless of whether, for example, one manuscript calls the famous Mozart opera "Die Zauberflöte" and another is labeled "The Magic Flute," or a small chamber music piece is called a "duet" on one manuscript but a "sonata" on another. Beyond Muscat, in the linked data environment, information on works—and the associated RISM records—can be integrated into web searches, online encyclopedias, and other external databases.

SRU interface

Muscat includes a SRU (Search / Retrieve via URL) interface. SRU is a standardized web service protocol used for searching databases in the Internet. In Muscat, the results of the search are issued in MarcXML format. The SRU interface opens up the possibility of various kinds of searches: full-text, by composer, or specified searches such as by library or other criteria. In addition, SRU search interfaces are available for personal names and libraries.

The SRU search interface can be used to create customized web-based catalogs based on any subset of the data stored in Muscat, such as for a particular library or country. In such cases, the SRU interface serves solely as the back-end infrastructure.

Interoperability with MEI

In recent years, the Music Encoding Initiative (MEI) has become increasingly used in scholarly projects dealing with music sources. For this reason, it is important for Muscat to be interoperable with this standard. To do so, Muscat leverages the fact that both its internal source description format (MarcXML) and MEI are in XML. This means that a transformation with the XML technology XSL can be used to export Muscat source descriptions directly to MEI.

comments for a source
The transformation of MarcXML Muscat source description to MEI can be performed via XSL.

Muscat currently embeds a default XSL stylesheet that performs this transformation. However, because the needs of projects concerned by this approach can vary, it is also possible to upload a custom stylesheet.

Music incipits in the MEI export can be left as Plaine and Easie incipits or converted to MEI encoding by Verovio.
