Ability to annotate OData metadata using the terms from a particular vocabulary.Ability to re-use or reference common micro-formats and vocabularies.To get us started I propose this set of goals: GoalsĪs with any new feature, we need to agree on a set of goals before we can come up with the right design. While this is powerful, it would be much better if it wasn't a 'guess', if the Producer used a well-known vocabulary to tell Consumers which property is the entity's location. Sesame does this by looking for specifically named properties, which it 'guesses' represent the entity's location. In fact some consumers are already trying to provide a higher fidelity experience, for example Sesame can render the results of OData queries on a map. It seems clear then that we need a mechanism that allows Producers to share more information that 'smarter' Consumers MAY understand enough to enable a higher fidelity experience.
While some problems are general enough that solving them inside OData adds value to the OData eco-system as a whole, most don't meet that bar. Each vertical brings its own specific set of requirements and challenges. OData is being used in many different verticals now. Vocabularies are not a new concept unique to OData, vocabularies are used extensively in the linked data and RDF worlds to great effect, in fact we should be able to re-use many of these existing vocabularies in OData. This navigation property is essentially a 'foaf:Knows ' relationship.This entity can be converted into an vCard.

A simple vocabulary might tell a consumer which property to use as an entity's title when displaying it in a form, whereas a more complex vocabulary might tell someone how to convert an OData person entity into a vCard entry. Vocabularies can range in complexity from simple to complex. They allow producers to teach consumers richer ways to interpret and handle data. Vocabularies are made up of a set of related 'terms' which when used can express some idea or concept.
