Tracking linguistic variation and equivalences

Fri, 01 Sep 2017 00:00:00 +0000

Model: MetaForm Project

State and University Library, Goettingen
Local "manifestations" of Dublin Core™ for specific projects introduce variations -- like "dialects"
"Crosscuts" -- how are elements used in different implementations?
Provides "mappings" and "crosswalks" between Dublin Core™ and other schemas of similar scope
Demonstrates the sort of output one would want from queries to a distributed registry

Requirements for the DCMI registry

Fri, 01 Sep 2017 00:00:00 +0000

Requirements for the DCMI registry

Users and implementors need

a dictionary of terms
a place to publish project- or discipline-specific adaptations to share with colleagues and partners

Registries as dictionaries

Fri, 01 Sep 2017 00:00:00 +0000

Metadata systems, like languages, need dictionaries for tracking usage and managing change

Like language dictionaries, registries can:

Prescribe good grammar and good usage guidelines
Describe how implementors are actually using metadata
Translate between natural languages
Define the "parts of speech" of metadata grammar -- building blocks of sentences

Registries as dictionaries

Namespaces versus Profiles

Fri, 01 Sep 2017 00:00:00 +0000

Implementors usually need to "mix and match"

use parts of one standard with parts of another
coin some local terms to fill in gaps
