NLM DailyMed DailyMed provides high quality information about marketed drugs. Drug labeling and other information in the SPL is what has been most recently submitted by drug companies to the Food and Drug Administration (FDA) as drug listing information.

OMG

Object Management Group (OMG) is a consortium, originally aimed at setting standards for distributed object-oriented systems, and is now focused on modeling (programs, systems and business processes) and model-based standards.

Model-driven architecture (MDA) is a software design approach for the development of software systems. It provides a set of guidelines for the structuring of specifications, which are expressed as models. Model-driven architecture is a kind of domain engineering, and supports model-driven engineering of software systems.

The MDA model is related to multiple standards, including the Unified Modeling Language (UML), the Meta-Object Facility (MOF), XML Metadata Interchange (XMI).
Of particular importance to model-driven architecture is the notion of model transformation. A specific standard language for model transformation has been defined by OMG called QVT.

The Ontology Definition MetaModel is an Object Management Group (OMG) specification to make the concepts of Model-Driven Architecture applicable to the engineering of ontologies. Hence, it links Common Logic (CL), the Web Ontology Language (OWL), and the Resource Description Framework (RDF).

NCI chose to use MDA because it is a set of standards that have worked well in other areas, and they
didn’t want to have to “reinvent the wheel.” The advantage to this approach is that MDA allowed NCI to use available tools to automatically
generate some of the code, while giving them the flexibility to tailor it to their specific needs. In the
future, when the system’s requirements change, they can update their models and quickly regenerate
the appropriate code.

The MDA model is related to multiple standards, including the Unified Modeling Language (UML), the The Object Constraint Language (OCL) is a declarative language for describing rules that apply to any Meta-Object Facility (MOF) Object Management Group (OMG) meta-model, including UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation. OCL is a key component of the OMG standard recommendation for transforming models, the Queries/Views/Transformations (QVT) specification.The Common Terminology Services 2.0 Specification will be an extension the HL7 CTS Specification, XML Metadata Interchange (XMI).
Of particular importance to model-driven architecture is the notion of model transformation. A specific standard language for model transformation has been defined by OMG called QVT.

The specifications produced by HL7 target multiple facets of the interoperability challenge, include specification of information models, data types, and vocabularies; messaging, clinical documents, and context management standards; and implementation technology, profile, and conformance specifications. Despite the diversity in depth and scope of HL7 specifications a common thread is the use of a model driven methodology and the derivation of specifications and interim work products from a common set of reference models. The models used in the HDF development methodology, use the Unified Modeling Language (UML) as the preferred syntax. The HDF closely aligns the underlying meta model governing well-formed HL7 models with the meta model of UML and applies the model driven process to all of the technical specifications of HL7, not just messages.

The Ontology Definition MetaModel (ODM) is an Object Management Group (OMG) specification to make the concepts of Model-Driven Architecture applicable to the engineering of ontologies. Hence, it links Common Logic (CL), the Web Ontology Language (OWL), and the Resource Description Framework (RDF).

The Object Constraint Language (OCL) is a declarative language for describing rules that apply to any Meta-Object Facility (MOF) Object Management Group (OMG) meta-model, including UML. The Object Constraint Language is a precise text language that provides constraint and object query expressions on any MOF model or meta-model that cannot otherwise be expressed by diagrammatic notation. OCL is a key component of the OMG standard recommendation for transforming models, the Queries/Views/Transformations (QVT) specification.

HL7 Static models are not strictly UML diagrams. Although they have some similarity in presentation, they are actually statements of constraints against a formal UML model, which is the RIM. In a static model, each of the "clones" is actually a statement of constraints on a properly defined RIM class (properly defined in the RIM sense). OCL constraints express additional rules that apply to the clone. In HL7 static models, OCL statements are applied to the clone - in other words, OCL statements are applied to the RIM class only when it is subject to the constraints defined in the clone. In order to use OCL with HL7 static models, a new binding mechanism must be described by HL7 (This is an expected extension to the OCL langauge).

The Common Terminology Services 2.0 (CTS2) Specification will be an extension the HL7 CTS Specification.

w3c recommendations

A W3C Recommendation is the final stage of a ratification process of the World Wide Web Consortium (W3C) working group concerning the standard. This designation signifies that a document has been subjected to a public and W3C-member organization's review. It aims to standardise the Web technology. It is the equivalent of a published standard in many other industries.

XML Schema, published as a W3C recommendation in May 2001, is one of several XML schema languages. Like all XML schema languages, XSD can be used to express a set of rules to which an XML document must conform in order to be considered 'valid' according to that schema. However, unlike most other schema languages, XSD was also designed with the intent that determination of a document's validity would produce a collection of information adhering to specific data types.

The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats.

RDF Schema (variously abbreviated as RDFS, RDF(S), RDF-S, or RDF/S) is an extensible knowledge representation language, providing basic elements for the description of ontologies, otherwise called Resource Description Framework (RDF) vocabularies, intended to structure RDF resources.

The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies. The languages are characterised by formal semantics and RDF/XML-based serializations for the Semantic Web. OWL is endorsed by the World Wide Web Consortium (W3C) and has attracted academic, medical and commercial interest.

SPARQL (pronounced "sparkle") is an RDF query language; its name is a recursive acronym that stands for SPARQL Protocol and RDF Query Language. It was standardized by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is considered a key semantic web technology.

SWRL (Semantic Web Rule Language) is a proposal for a Semantic Web rules-language, combining sublanguages of the OWL Web Ontology Language (OWL DL and Lite) with those of the Rule Markup Language (Unary/Binary Datalog).
