The eProcurement Ontology v3.0.0 release includes the following features:

• Attributes were consistently added with the “has”/“is” prefix in order to conform to the convention that attribute and relation names must start with a lowercase letter. Previously all attributes started with the capital letter.
• Attribute types were migrated from UML and epo datatypes into XSD/RDFS datatypes. The inventory of used data types is provided in the datatype package of the model.
• Packages have been reorganised as presented below.
• New modules (as EA root nodes) have been created (organisation and inventory to be provided elsewhere). Some classes from the epo module were moved into other modules for future modelling, as may be mentioned in this document as deleted.
• The main requirements considered in this refactoring exercise was conformance to a) eForms and b) TED Standard Forms.
• The conceptual guidelines considered in this refactoring were a) pinning of the concepts under an upper level ontology, while taking into consideration b) multi phase life cycle of the procurement process.
