Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members
of ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations,
governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of
information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication
as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 19763-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information Technology,
Subcommittee SC 32, Data management and Interchange.
ISO/IEC 19763 consists of the following parts, under the general title Information technology — Metamodel
framework for interoperability (MFI):
Part 1: Framework
Part 3: Metamodel for ontology registration
Part 5: Metamodel for process model registration
Part 6: Registry summary
Part 7: Metamodel for service model registration
Part 8: Metamodel for role and goal model registration

Introduction
Due to the proliferation of internet-enabled communication aided by mobile devices, social network
systems and cloud computing, both the efficient and effective sharing of information and the handling of
business transactions across countries and cultures has become easier.
In the private sector the handling of these business transactions using Electronic Data Interchange (EDI)
has been common for a long time. Companies hold large quantities of structured, semi-structured and
unstructured data – the “Big Data” explosion. It is in their interest to make effective use of this data to
extract business intelligence and knowledge.
In the public sector, governments in many countries and territories are working on the establishment of
new schemes that enable interoperation and collaboration among different departments or agencies,
materialising the semantic interoperability of data and surmounting border and/or language differences. At
the same time, many governments and agencies are attempting to make their data available to their
citizens over the internet, the “Open Data” initiatives. These “Open Data” initiatives could be the driver for
similar innovations in the private sector. One of the issues for users is to access the various sets of open
data easily and integrate them for analysis so as to create new value through added information or
knowledge.
These trends have produced new needs for standards that enable effective information sharing in both
private and public sectors.
One of the key enablers of this sharing of the information that is used by different communities through the
interoperability of systems is a registry, or a network of inter-connected registries, that provides for the
discovery and sharing of meta-information, such as metadata or models. The Metamodel Framework for
Interoperability (MFI) provides the specifications for such registries.
The MFI specifications can be considered as an extension of those for a Metadata Registry (MDR) as
defined in ISO/IEC 11179-3 because MFI and MDR share the same registration mechanism and
procedures. In 2010 a special study project was initiated to consider the harmonisation of MDR and MFI
and a key recommendation of that study project was that the common facilities should be identified and
used for both MDR and MFI. It is anticipated that MDR and MFI could be more closely related and
integrated, leading to benefits for the users who need more effective sharing of information and models, or
more sophisticated interoperation of systems.
This new edition of Part 1 has been developed to provide a clear overview of MFI and to illustrate the
overall architecture of the MFI family of standards to reflect the major changes described above.

INTERNATIONAL STANDARD
Information technology – Metamodel framework for
interoperability (MFI) – Part 1: Framework
1 Scope
1.1 Inclusions
This is a part of the ISO/IEC19763 (Metamodel framework for interoperability) (MFI) family of standards.
As the first part of MFI, this part provides an overview of the whole of MFI. In particular, the purpose, the
underlying concepts, the overall architecture and the requirements for the development of other standards
within the MFI family are described.
MFI provides a set of normative metamodels to enable the registration of many different types of model.
Each of these metamodels is expressed as a UML Class Diagram.
MFI is evolving. Currently, in addition to this part, the MFI family comprises:
• A core model and facilities for the basic mapping of models (Part 10)
• A metamodel for ontology registration (Part 3)
• A metamodel for process model registration (Part 5)
• A metamodel for service model registration (Part 7)
• A metamodel for role and goal model registration (Part 8)
• A Technical Report describing on demand model selection based on RGPS (Role, Goal, Process
and Service) (Part 9)
• A metamodel for information model registration (Part 12)
• A metamodel for form design registration (Part 13)
• A metamodel for a registry summary (Part 6)
These parts are described in more detail in Annex A.
1.2 Exclusions
The MFI does not specify any physical structure of the registry where model information is to be recorded.
MFI metamodels define standard views as models to be used in the registering of model instances in a
model registry while actual instance documents could be stored in a model repository.

2 Conformance
This part of ISO/IEC 19763 specifies no conformance requirements. Other parts of the ISO/IEC 19763
family of standards specify their own conformance requirements as appropriate.

5 Purpose and objectives of MFI
5.1 Purpose of MFI
MFI provides a set of specifications that allow the registration of models to facilitate interoperability among
systems or persons. In this context interoperability is interpreted in its broadest sense: the capability to
communicate, execute programs, or transfer data among various functional units in a manner that requires
the user to have little or no knowledge of the unique characteristics of those units (ISO/IEC 2382-1:1993).
The models that are registered may be ontologies, information models, process models, service models,
models of roles and goals or any other type of model specified within MFI.
Models are used widely within the information technology community to represent system requirements
and system specifications. These models can be expressed using a variety of notations or languages. An
information model may be expressed in any one of a number of entity-relationship notations, from the
simplicity of
