Each ARC node emphasizes and requires different elements of the ARC RDF Schema. See below for samples of MESA RDF and recommendations from the Directors for metadata contributions.

Sample RDF

Requirements and Recommendations

In addition to the general ARC RDF specifications, MESA has the following requirements and recommendations for specific fields for projects in the MESA federation.

Required

<collex:discipline>

the discipline or disciplines represented by the object.
Required? YES
Can appear? MULTIPLE
Available Discipline Values
Anthropology Archeology Architecture Art History
Book History Classics and Ancient History Film Studies Ethnic Studies
Gender Studies Geography History Law
Literature Mathematics Musicology Philosophy
Religious Studies Science Theater Studies
This is a seed list and may be expanded, with the approval of the ARC Steering Committee and Directors
A value of Languages and Literatures requires the addition of a @lang attribute to collex:discipline, the value of the attribute being the ISO language code for the appropriate language. Multiple codes may be contained in a single @lang attribute, with spaces between each code.

Recommended

<dc:type>

the physical medium of the object.
Required? NO
Can appear? ONCE
MESA recommends using the Getty Art & Architecture Thesaurus (AAT) as a term vocabulary

<dc:provenance>

a statement of any changes in ownership and custody of the object since its creation that are significant for its authenticity, integrity, and interpretation.
Required? NO
Can appear? MULTIPLE

<dc:subject>

a single keyword which is not currently displayed, but may be applied to tags and for future mining of data from ARC Partners sites.
Required? NO
Can appear? MULTIPLE
MESA requires that subject terms come from a recognized authority list, or the authority list must be approved by the MESA Steering Committee and Directors.

<dc:language>

This element identifies the language of the text inscribed in or on the object (distinct from the culture of the object, which should be indicated using dc:subject)
Required? NO
Can appear? MULTIPLE
MESA requires using the language codes from the ISO 639-2 Language Code List. The content of dc:language may be either from the first column (ISO 639-2 Code), the third column (English name of Language), or the fourth column (French name of Language).

Converting to MESA RDF

There are several programmatic ways to convert from project metadata (be it in a database, XML, or some other format) into the MESA-specified RDF.

Example XSLT conversions are available on the XSLT section of the Collex wiki.

Jeffrey Witt, editor of the Petrus Plaoul Electronic Critical Edition, one of the MESA partner projects, has created a Ruby script to automate creation of his project's RDF files. It is tailored to suit the Petrus Plaoul project, but is customizable to other locations and other types of data (particularly TEI). The Ruby script is available at https://bitbucket.org/jeffreycwitt/rdfbuilder/, and Dr. Witt has generously offered to help others customize it - you can contact him at jeffreycwitt@gmail.com.
