The Smart Publisher's Guide to LRMI Tagging. (Jul 2014) The newly updated edition of this practical guide jncludes best practices for
organizing the metatagging process and workflow and a helpful tagging
checklist. This new edition also features an expanded appendix that walks the
user through a step-by-step application of the LRMI tagging process, using
content examples from Rosen Publishing tagged through the Illinois Shared
Learning Environment (ISLE) tagger portal.

Shapes

Thu, 24 Jan 2019 00:00:00 +0000

Following a landmark workshop on RDF validation in 2013, two languages have emerged for describing the "shape" of graph structures for the purpose of validating RDF data. The Shape Expressions Language (ShEx) and Shapes Constraint Language (SHACL) provide languages for expressing constraints against which graphs of RDF triples can be compared. These languages support the expression of a Dublin Core™ application profile in a manner that can directly be used for validating metadata based on the profile.

Concept Scheme

Thu, 24 Jan 2019 00:00:00 +0000

Concept Scheme is basically a synonym for Ontology, though concept schemes are most commonly associated with Simple Knowledge Organization System (SKOS), a data model for knowledge organization systems that was designed for maximum semantic simplicity.

Vocabulary

Wed, 23 Jan 2019 00:00:00 +0000

In Semantic Web usage, Vocabulary is a near-synonym for Ontology though "trend is to use the word ontology for more complex, and possibly quite formal collection of terms, whereas vocabulary is used when such strict formalism is not necessarily used or only in a very loose sense." Whatever else they might be called, DCMI Metadata Terms, the AGROVOC concept scheme, and the Bibliographic Ontology (BIBO) are also vocabularies.

Domain Includes and Range Includes

Wed, 23 Jan 2019 00:00:00 +0000

Domain Includes and Range Includes are used to suggest classes to which, respectively, the subject or object of an RDF statement may belong. In contrast to formal domains and ranges, domain and range includes are less about enabling logical inference than about helping users understand how a given property is intended to be used. Drawing a lesson from the successful Schema.org initiative, the DCMI Usage Board decided in 2018 to soften many of the formal domains and ranges added in 2008 to domain and range includes.

Competency Index

Wed, 23 Jan 2019 00:00:00 +0000

A Competency Index is a set of topically arranged assertions of the knowledge, skills, and habits of mind required for professional practice in a given area of practice. DCMI's Linked Data Competency Index, for example, provides an overview, or map, of the Linked Data field both for independent learners who want to learn Linked Data methods and technology, and for professors or trainers who want to design and teach courses on the subject.

Metadata Basics

Sat, 15 Dec 2018 00:00:00 +0000

A brief introduction to DCMI by Tom Baker as presented at the DCMI Virtual 2021 conference, 4 October 2021 (YouTube).

Application Profile

Sat, 15 Dec 2018 00:00:00 +0000

An application profile is a metadata design specification that uses a selection of terms from multiple metadata vocabularies, with added constraints, to meet application-specific requirements. In the Dublin Core™ context, application profiles are ideally based on, or compatible with, vocabularies defined in RDF.

Open World Design

Mon, 30 Apr 2018 00:00:00 +0000

Open World Design accepts that information exists in a global context that is evolving in unpredictable ways and avoids assuming that interoperability with future, possibly unanticipated sources can be more than partial. Open World Design stands in contrast to the Closed World Design of traditional IT environments, in which data is carefully controlled, with document formats and database schemas optimized for specific applications. Loosely specified vocabularies such as Dublin Core, when used with generic underlying models such as RDF, provide a good technological basis for Open World Design.

From the LRMI Metadata Meetup, July 2014

The LRMI Education Metadata Update in Washington, DC, featured more than a
dozen presenters discussing LRMI usage in a variety of settings: statewide
education initiatives, developers/solutions providers, content
providers/curators, and nonprofit institutions.

To present these examples in a concise form we use the Turtle syntax for RDF. The examples therefore appear in code lines such as:

Dumb-Down Principle

Tue, 20 Nov 2012 00:00:00 +0000

The Dumb-Down Principle, which entered Dublin Core™ discourse in 1998, denoted a principled way of viewing a complex metadata description through the lens of a simpler representation, typically Simple Dublin Core.

Vocabulary Encoding Scheme

Sun, 12 Aug 2012 00:00:00 +0000

Vocabulary Encoding Scheme (VES) is a DCMI-specific synonym for the identifier of a SKOS Concept Scheme. Starting with the Dublin Core™ Qualifiers specification of 2000, DCMI coined VES URIs as a way to indicate the source of string values from published controlled vocabularies such as the Library of Congress Subject Headings (LCSH). For example, the string value Textile design--China--History could be marked as coming from LCSH by tagging it with the DCMI-coined VES URI http://purl.org/dc/terms/LCSH. With the widespread conversion of controlled vocabularies such as LCSH into SKOS after 2009, the Vocabulary Encoding Scheme has become less relevant as a type of metadata term.

Syntax Encoding Scheme

Sun, 12 Aug 2012 00:00:00 +0000

Syntax Encoding Scheme is a DCMI-specific synonym for RDF Datatype. An RDF Datatype indicates that a given literal represents a resource of a given type, such as a Gregorian calendar date, Boolean value, integer, or natural-language character string. Datatypes are identified by URI and associated with literals using RDF syntax.

DCMI Metadata Terms

Sun, 12 Aug 2012 00:00:00 +0000

The Properties, Classes, Vocabulary Encoding Schemes, and Datatypes declared and maintained by the Dublin Core™ Metadata Initiative are collectively referred to as DCMI Metadata Terms. Property, Class, and Datatype (aka Syntax Encoding Scheme) are defined exactly as in RDF, while a Vocabulary Encoding Scheme is equivalent to the identifier for a SKOS Concept Scheme.

Encoding Scheme

Thu, 14 Jun 2012 00:00:00 +0000

The Encoding Scheme entered Dublin Core™ discourse at a 1997 workshop in Canberra, Australia. As originally defined, a Scheme was a Qualifier that "specifie[d] a context for the interpretation of a given element". In 2000, the encoding scheme was differentiated into the Syntax Encoding Scheme and Vocabulary Encoding Scheme.

Metadata Interoperability

Tue, 17 Jan 2012 00:00:00 +0000

In contrast to "metadata harmonization", metadata interoperability is "the ability of two or more systems or components to exchange descriptive data about things, and to interpret the descriptive data that has been exchanged in a way that is consistent with the interpretation of the creator of the data" (Mikael Nilsson).
