MMI Ontology Metadata for Community Ontologies

Some ideas about important metadata to capture in community ontologies

Introduction

This document contains some ideas about what our ontology repository needs to track (and show) to be good community citizens.

These started as a quick brainstorm by John Graybeal, but serve as a good starting point for actual requirements/fields to implement.

Description of Fields

Descriptions containing '[OMV]' originated in the Ontology Metadata Vocabulary for the SemanticWeb (Palma, Hartmann, Haase, et al), version 2.4.

Fields containing '[0..n]' may appear multiple times.

Vocabulary Terms contains the controlled vocabulary terms that are used to fill out the field.

Priority contains the best estimate of near-term needs for the Ontology Server contents.

The Embed column indicates whether the metadata should appear as embedded metadata in the ontology as it is served by MMI.

Priority Codes

Must have
Extremely desirable
Very desirable
Desirable
Useful
Mildly Useful

Embed Codes

Y: Metadata should be embedded with ontology
A: Metadata may be embedded with ontology as that becomes appropriate, but is not required
N: Metadata should not be embedded with ontology
?: Not clear if metadata should not be embedded with ontology

Original Source Vocabulary: General Information

Field ID	Description	Vocabulary Terms	Priority	Embed
OSI.1	Physical location (URL) of original source vocabulary (may be different than XR.1; this one is where the vocabulary is accessed)		1	Y
OSI.2	Format of source vocabulary (may be different than XR.2)		4	N
OSI.3	Manager of source vocabulary (may be multiple, see role) [0..n]		2	A

OSI.7	Web site URL describing/providing context for vocabulary [0..n]		3	?
OSI.9	Ontology Original Metadata: These metadata items repeat metadata in the original ontology (or vocabulary, if applicable). They may be copied into the fields in Ontology Metadata, if that is appropriate. It may be appropriate to create a more extensive list here that is in the image of the Ontology Metadata fields below.

Original Source Vocabulary: Cross-Referencing

Used to point people from our copy of vocabulary and its terms to the original content.

The metadata for individual terms is not maintained in the ontology metadata, but is annotated for each term.

XR.1	Source vocabulary URI		3	Y
XR.2	Source vocabulary URI type	URN, URL	4	A
XR.3	Base term URI (if different for different terms, may be unique for each term)		3	Y*
