Dublin Core announces openWEMI for community review

openWEMI is an RDF vocabulary based on the concepts of Work, Expression, 
Manifestation, and Item (WEMI) that were first introduced in the 
Functional Requirements for Bibliographic Records (FRBR) document 
produced by a working group of the International Federation of Library 
Associations (IFLA). That work and subsequent versions form the 
theoretical basis for library catalog metadata.

This DCMI work product defines a minimally constrained set of classes 
and properties that can be used in a variety of contexts. Unlike the 
IFLA work, openWEMI elements are purposely defined without reference to 
library catalog functions. Because the openWEMI elements are defined 
broadly and with minimal constraints, metadata models are likely to use 
openWEMI elements as superclasses and super-properties to the more 
specific resource types being defined.

The proposal includes the class Endeavor, which is the superclass to the 
WEMI classes; this provides a semantic grouping of the WEMI entities. 
openWEMI also includes properties (commonWork, commonExpression, 
commonManifestation, commonItem) that can be used to make statements 
about any resources defined in metadata, even those not organized around 
WEMI concepts.

The openWEMI primer [1] introduces the vocabulary and its uses. The RDF 
vocabulary has human-readable documentation [2] and a downloadable 
turtle file [3]. Note that the vocabulary uses a temporary namespace 
pending review and comments.

Comments, suggestions, and corrections can be addressed as github issues 
[4] or on the openWEMI mailing list [5].
