What is an O-DEF Extension?
While we have defined a set of core objects and properties in the Open Data Element Framework (O-DEF), Version 1.0, these cover only the highest level object classes and properties. To tailor these to meet the needs of specific use cases, the O-DEF can be extended. For example, the 'Date' identifier is given the value '10' in O-DEF v1.0; but this is refined in the Date Property Core Index Extensions of the O-DEF™ to give a series of new identifiers, such as:
- 10.1 Date.Birth: A date on which a person or animal was born.
- 10.2 Date.Deceased: A date on which a person or animal died.
- 10.3 Date.Marriage: A date on which a couple marries.
- 10.4 Date.Effective: A date from which onward a condition applies.
- 10.5 Date.Expiration: A date until which a condition applies.
Extensions are created and defined by the the Semantic Interoperability Workgroup, within the Open Platform 3.0 Forum of The Open Group; to join the conversation, please see the How to Get Involved tab above.
To request extensions for inclusion in the O-DEF standard, please contact us.
The following extensions are available to download from the Open Group Library:
A snapshot of what is intended to become an Open Group Standard for the Amount Property Core Index Extensions of the Open Data Element Framework (O-DEF) – the Amount Property Extensions. This extension will enable greater flexibility and clarity in the types of “amounts” available for use in the O-DEF classifications of data elements.
