The ASN profiling language provides communities and organizations with the means to define profiles of the ASN to meet particular needs through inclusion of additional properties and classes from other namespaces and definition of constraints on data patterns. ASN profiling is based on the Dublin Core's conceptualization of application profiles and description set templating as well as refinements to these conceptualizations developed by the U.S. Library of Congress to support BIBFRAME profiling.
The ASN Description Framework (ASN-DF) is a graph-based metamodel for creation of 1-n ASN profiles for the description of competency frameworks defined by national, regional and organizational bodies (jurisdictions). The ASN-DF assumes that no single, tightly defined schema for describing competency frameworks will meet all needs. Instead, the ASN-DF provides the means to "profile" the ASN through extension, refinement and augmentation to meet particular needs. It is through such profiling of the ASN that different jurisdictions and entities define their own solutions while maintaining the ability for their metadata to be harmonized across profiles. ASN Profiles also provide the means for local constraints on acceptable data (i.e., defining data "rules" on specific RDF graphs) to be communicated to others. To achieve these goals, the ASN-DF provides a small vocabulary of classes and properties and a set of mechanisms for tailoring an ASN Profile to handle particular jurisdictional, organizational or application needs.
[ASIDE: A "profile" in the sense meant here is a means of instantiating "closed world assumptions" in a given context.]
[ASIDE: In similar vein, the ASN DF defines a vocabulary/ontology and encourages multiple other (unrelated) entities to create and maintain extension and refinement sets of constraints on the ASN vocabulary/ontology without violating it.]
This ASN Briefing will illustrate development of new ASN profiles using the mechanisms provided by the ASN-DF. An example of the United States Profile in JSON can be viewed here.
For a general introduction to the ASN-DF, it's uses, properties and classes, see ASN-DF Schema.
A jurisdiction's ASN Profile is an information model for describing competency frameworks that is based in the ASN-DF and particularized for the jurisdiction through the processes of:
refinement (definition of subclasses and subproperties of existing ASN classes and properties);
extension (use of properties and classes either newly created for use with the specific ASN Profile or reused from other ontologies); and
value constraints (restricting the permissible value datatypes or classes).
The result of these processes of refinement, extension and value constrain definition is a declarative specification of the particular "RDF data shape" required for a jurisdiction's RDF data to be deemed "conforming". The resulting "shape" provides implementers with both a means of unambiguously communicating about the Profile and developing mechanisms for validation of data conforming to it. By being declarative and stating the validation intent rather than the validation method, an ASN Profile description is useful in many different implementation scenarios including development of data validation mechanisms using deployed solutions such as Stardog ICV, IBM's Resource Shapes, TopQuadrant's SPIN (a W3C Member Submission), and SPARQL.
An ASN Profile document has two fundamental parts: (1) a set of template-defining tables based in the ASN Profile Grammar (see section 3 below) that describe the Profile's permissible resource classes, the object and datatype properties associated with those classes, and the constrains on permissible property values (i.e., value vocabularies and datatypes); and (2) a JSON serialization of the resulting constraints defined in the tables.
FIG 1. below illustrates the basic templating structure of an ASN Profile document:
a profile template for describing the Profile itself;
resource templates describing the resource classes making up the Profile;
an array of property templates defined for each resource class that are used to describe the possible metadata structure of a "record" conforming to the Profile; and
value constraint templates defining constraints to be applied to properties that restrict the permitted values associated with the property templates.
The following Extended Backus-Nuar Form describes the syntax used in Appendix A to describe the essential ASN Profile syntax elements for defining the templates. The ASN grammar extends the BIBFRAME grammar defined in BIBFRAME Profiles: Introduction and Specification through addition of the allowedValueURI value constraint to support specification of "pick lists" of resource classes.
Profile ::= id | title | description | date | contact | remark | resourceTemplates*
resourceTemplates ::= id | resourceURI | resourceLabel | remark | propertyTemplates*
propertyTemplates::= propertyURI | propertyLabel | mandatory | repeatable? | type |
valueConstraint | remark
valueConstraint ::= valueLanguage | languageURI | languageLabel| valueDataType | valueTemplateRefs |
allowedValueURI | editable | defaultURI | remark
valueDataType ::= dataTypeURI | dataTypeLabel | dataTypeLabelHint | remark
valueTemplateRefs ::= editable | defaultURI | defaultLabel
mandatory ::= "true" | "false"
repeatable ::= "true" | "false"
editable ::= "true" | "false"
id ::= URI
resourceURI ::= URI
propertyURI ::= URI
languageURI ::= URI
dataTypeURI ::= URI
valueTemplateRefs ::= URI
allowedValueURI ::= URI
defaultURI ::= URI
type ::= literal | resource
literal ::= valueLanguage | languageURI | languageLabel | valueDataType
resource ::= valueTemplateRefs | editable | defaultURI
Many jurisdictions and other entities that create competency frameworks have existing authority files, controlled vocabularies, taxonomies and thesauri defining acceptable values for concepts such as education levels and subjects. These vocabularies provide significant jurisdiction-specific context to the Profile; and, therefore, they should be used to constrain data values. Such authority files and controlled vocabularies may be currently expressed as simple text terms or be modeled as contextual classes using a description language like W3C's Simple Knowledge Organization System (SKOS). We strong recommend that consideration be given to modeling a Profile's key vocabularies as skos:ConceptScheme classes with individual concepts of the class skos:Concept.
When controlled vocabularies and authority files are modeled as a skos:ConceptScheme with concepts defined as skos:Concept, instead of expressing a U.S. education level as being "Grade 5", the value can be identified as a member of a concept class using the U.S. URI <http://purl.org/ASN/scheme/ASNEducationLevel/5> from the ASN-US Education Level Vocabulary. Similarly, the subject concept of "Statistics & probability" could be more usefully named as <http://vocabulary.curriculum.edu.au/scot/2570> from the Australian Schools Online Thesaurus (ScOT) . Expressing these various concept terms as members of formal classes makes it possible to use them as Linked Data "glue" and guarantees uniformity of use and machine readability that is lacking with terms encoded as plain literals.
Therefore, every effort should be made in developing an ASN Profile to convert "strings" to "things"—i.e., from literals to linkable resources identified by resolvable URI.
