| - | [[dido:public:ra:xapend:xapend.a_glossary:i:interoperability]] is a characteristic of a product or system, whose interfaces are completely understood, to work with other products or systems, present or future, in either implementation or access, without any restrictions. However, there are different levels of interoperability. The lowest most basic level of interoperability is at the network level. The degree of interoperability increases in difficulty as one moves up the interoperability levels. The most difficult level is the semantic level, at this level two assets can communicate with little or no prep work using common detailed formal, machine readable [[dido:public:ra:xapend:xapend.a_glossary:o:ontology | Ontologies]] including a vocabulary of terms. | + | [[dido:public:ra:xapend:xapend.a_glossary:i:interoperability]] is a characteristic of a product or system whose interfaces are completely understood to work with other products or systems, present or future, in either implementation or access, without any restrictions.

| - | Foundational or Technical Interoperability Level is concerned with the most fundamental and basic kind of interoperability. It provides the "foundation" on which the other kinds of interoperability are built upon. It identifies the technical aspects of peer-to-peer interoperability regardless of hardware, operating system, or [[dido:public:ra:xapend:xapend.a_glossary:m:midware|middleware]] platforms. There are two perspectives to the Foundational or Technical Interoperability Level: Data and System. | + | The //Foundational// or //Technical Interoperability Level// is concerned with the most fundamental and basic kind of interoperability.
