Abstract : The Mineralogy extension is a standardized lexicon developed by the Mineralogy Extension Task Group to improve the distribution of information pertaining to mineralogy collections. The expansion comprises a compilation of knowledge organization resources, focused on the normative term list, incorporating support for the Compound Specimen Model, various classification systems, and an expanded array of geologic contexts.

1 Introduction

1.1 Status of the content of this document

Sections 2 through 3 are normative, except for Table 1. In Section 4 and its subparts, the values of the Normative IRI, Definition, Required, and Repeatable are normative. The value of Usage (if it exists for a given term) is normative in that it specifies how a borrowed term should be used as part of Latimer Core. The values of Term Name is non-normative, although one can expect that the namespace abbreviation prefix is one commonly used for the term namespace. Labels and the values of all other properties (such as notes) are non-normative.

1.2 RFC 2119 key words

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

1.3 Categories of terms

2 Borrowed Vocabulary

Table 1. Vocabularies from which terms have been borrowed (non-normative)

3 Namespaces, Prefixes and Term Names

The namespace of terms borrowed from other vocabularies is that of the original. The namespace of de novo Mineralogy Extension terms is http://rs.tdwg.org/mineralogy/terms/. In the table of terms, each term entry has a row with the term name. This term name is generally an “unqualified name” preceded by a widely accepted prefix designating an abbreviation for the namespace It is RECOMMENDED that implementers who need a namespace prefix for the MinExt namespace use minext. In this web document, hovering over a term in the Index By Term Name list below will reveal a complete URL that can be used in other web documents to link to this document’s treatment of that term, even if it is from a borrowed vocabulary. It is very important to note that some vocabularies, e.g those of the Dublin Core Metadata Initiative (DCMI), provide versions of the same term in two different namespaces, one providing for string values and one providing for IRIs, even where that separation is simply a recommendation, not a mandate. See this DCMI wiki entry on this topic.

4 Metadata Terms

The normative documentation provided below utilizes a set of standardized metadata terms. These are defined as follows:
