1 Background

The Achievement Standards Network (ASN) Description Framework (ASN-DF) is comprised of a core set of Resource Description Framework (RDF) properties and classes that can be combined in community profiles with properties and classes defined by others to describe competency frameworks. This documentation describes only those properties and classes defined in the ASN namespace. To see how these terms are combined with those defined by others into a community or organization profile that expresses particular descriptive needs, see ASN Profiles.

The core RDF namespace described here provides IRIs for vocabulary terms useful in RDFa markup and in development of application profiles in the manner defined by Dublin Core. Custom community application profiles for competency frameworks that meet particular national or project needs can be designed using: (1) properties and classes from the ASN Core namespace, (2) locally defined sub-classes and sub-properties of the ASN terms; and (3) other RDF schemas and ontologies useful in the context of the application profile.

The ASN-DF schema is available in a RDF/XML serialization.

Development of the ASN-DF dates back to 2000 and gained significant momentum with near decade-long funding from the U.S. National Science Foundation (NSF) starting in 2002 to the Information School at the University of Washington and its collaborator, JES & Co., a U.S. non-profit. The goals of the NSF funding were two-fold:

ASN-DF: to design a description framework for machine encoding of the competencies guiding K-12 STEM education in the U.S.; and, to promote it's wide, international adoption as a defacto standard; and
ASN-US: to develop a U.S. repository of competency frameworks for K-12 based on the ASN-DF.

In 2007, a the University of Washington and JES & Co. began a cooperative endeavor with Link Affiliates to advise in development of the Australian ASN-DF profile and collaborate on needed tool development to support the emerging competency framework ecosystem based on the ASN-DF. Work is currently underway on the frameworks of the Canadian provinces.

Subsequent support for the ASN was provided by the Bill & Melinda Gates Foundation. In 2013, stewardship of the ASN-US repository was transferred to D2L with a commitment to maintain access to the repository as an open, public service.

5 Conceptual Model

The ASN Conceptual Model is framed in terms of two entities:
1. The asn:StandardDocument representing the promulgated competency framework as a whole; and
2. The asn:Statement representing an individual achievement assertion in an instance of asn:StandardDocument. The asn:StandardDocument is comprised of a set of related instances of asn:Statement.
All instances of asn:StandardDocument and asn:Statement conforming to the ASN Conceptual Model are identified by globally unique identifiers in the form of IRI that are dereferencable over the Web.
A set of core properties define the relationships between the asn:StandardDocument and asn:Statement and between statement dyads. The relationships defined in the core are of two types:
1. Structural relationships: Structural properties are responsible for replicating the necessary structural relationships between components of the standards document—e.g., structuring hierarchies of instances of asn:Statement in the form of taxon paths and establishing the relationship between an instance of asn:StandardDocument and its set of component asn:Statement.
2. Semantic relationships: Semantic properties define relationships of meaning between statements including assertions of equivalence or other forms of conceptual synergy of any useful sort. For example, the asn:crossSubectReference property asserts that the instance of asn:Statement in one asn:StandardDocument is related in an interdisciplinary manner to a asn:Statement in a second asn:StandardDocument.
The statement entity is of two kinds—original and derived:
1. Original statements: Statements in standards documents formally promulgated by a jurisdiction are called original statements in the ASN. Original statements are jurisdictionally binding.
2. Derived statements: Third parties may create derived instances of asn:Statement that refine an asn:Statement originally coined by another. Derived statements have no jurisdictional binding and are clearly identified as "derived." For example, a 3rd party may create in its own namespace a derived asn:Statement or a set of such statements that decompose an an original asn:Statement into more granular expressions to meet particular business needs. Conformant derived statements, like original statements, are identified by URI, are described using ASN statement properties (or property refinements) and utilize appropriate structural and relational properties associating them with original statements and other derived statements.
The set of core ASN properties is extensible. The current set of properties will be extended to support additional structural and semantic relationships as they emerge in standards documentation and in use of standards data.
At a minimum, dereferencing a standards document or original or derived statement IRI must return the metadata describing the entity identified by the URI including any structural and semantic references to other ASN entities. Such returns should be in machine-readable RDF serialized in JSON-LD, Turtle, or RDF/XML.

The following figure illustrates the entities and select relationships in the ASN Conceptual Model.

6 ASN Terms—Properties & Classes

Properties

The format and content of the ASN property tables are summarized below:

Property URI	A Uniform Resource Identifier used to identify the property.
Label	A human-readableLabel assigned to the property (May be represented in different languages.)
Defined By	An identifier of a namespace, pointer to a schema, or bibliographic reference for a document within which the property is defined.
Source Definition	The definition of the property in the namespace in which the property was originated. (May be represented in different languages.)
Source Comment	Comments on the property from the namespace in which the property originated. (May be represented in different languages.)
Type of Term	The grammatical category of the term ("Property", "Class").
Refines	The described property semantically refines the referenced property. A refinement makes the meaning of the element narrower or more specific as defined in the DCMI Abstract Model (http://dublincore.org/documents/abstract-model/). It will share the meaning of the unrefined element but with a more restricted scope.
Property Domain	The domain of the property being defined identifies the class(es) that may be acceptable instances of the subject of RDF statements for the property.
Property Range	The range of the property being defined identifies the class(es) that may be acceptable instances of the object of RDF statements for the property.
Usage Note	A comment on the usage of the property or class (`vann:usageNote`).
Equivalent Property	The property being defined is equivalent to the property indicated (`owl:equivalentProperty`).

[1] Editor's Note: Where possible, the ASN is dedicated to the reuse of existing, meaningful terms (properties & classes) defined in other namespaces—e.g., Dublin Core, FOAF, SKOS—and tries not to "coin" new terms except where there are no suitable existing terms. Thus, the ASN-DF does not include every property frequently used in creating ASN-DF profiles. For example, the ASN-US profile utilizes the following additional terms:

Example(s) use from Library of Congress (LC):
- loc:author
Example(s) use from Dublin Core Terms (dcterms):
Example(s) use from Dublin Core 1.1 (dc):
Example(s) from Gateway to Educational Materials (gem):
- gem:hasChild
- gem:isChildOf
Example(s) from Simple Knowledge Organization System (skos):
- skos:note

An XML element and an RDF property are not equivalent since they are based in distinct information models (hierarchy (i.e., document tree) vs. graph). Where a useful element exists that is defined in an XML schema but not as an RDF property, consideration should be given when creating an ASN-DF profile to creating an RDF property in a namespace controlled by the profile creator with appropriate attribution of the XML schema—unless such an RDF derivation is prohibited by the creators of the XML schema.

For a full discussion and illustration of "profiles", see Introduction and Specification of ASN "Profiles".
