About the Xesam Ontology

Source and Content

All objects are characterized by two main properties; Source and Content. These are read as fields on the object and in addition to characterizing the type and representation of the object also imply which other fields to expect.

• Source: The physical representation of the object.

  Content: The abstract interpretation of the object.

And example could be an office document stored on the harddisk. It would have source File and content Document.

Categories and Fields

Source and Content are called categories. Categories deal with the abstract interpretation of an object. For example both an .odt and a .pdf file is a TextDocument even though the file formats are different. The Xesam ontology categorizes data in two ways - how it is stored (source) and what the data represents to the user (content).

A field is a named variable that contains information about an object. For example an Image has a height and a width field, and a TextDocument has a wordCount.

A category defines what fields make sense on an object belonging to it. These fields are not guaranteed to be set though. For example the Image content category defines that height and width (and others) makes sense on these types of objects, but wordCount does not make sense on an Image object.

Relations to Mime Types

By definition the mime type of a file (or more generally a stream) is strictly related to the format of the contents. Mime types live in a hierarchy defined by a sub-class-of-relation. This means that an SVG image file is both a text/xml and image/svg+xml. The Xesam ontology uses similar hierarchical grouping, the key difference is that the mime types do not define a generic Image mime type because it only deals with formats, the Xesam ontology on the other hand is primarily about the categorization of the file where a generic Image class makes perfect sense.

Read the Shared Mime Spec on freedesktop.org for more information about mime types.

Hierarchical Structure

Both fields and categories are linked in a hierarchical type system by a sub-class-of relation. This means that all items in the ontology can have multiple parent types as well as multiple children. Consider a photography stored in a .jpg on the harddisk. The content type is Photo, which is again an Image, and Image is more generally a Media object and so on. The source type is File which is more generally a Filelike object.

The same structure is imposed on fields. Consider the to: field of an email. It is more generally a primaryRecipent and even more abstractly just a recipent.

Searching Using the Xesam Ontology

If you are interacting with any Xesam search or metadata services it is important to know how the type hierarchy works in that context. The rule is simple; searching in a category or field will also match in any child of that category or field. Here are two examples

• If you search for all objects with "Michael" in the recipent field, then objects with "Michael" in the primaryRecipent or to fields are also matched.

• Searching for all objects in the Visual category with a height of 128, will get you both Image, Photo, and Video objects with a height of 128.

Availabale Ontologies

The Xesam ontology as a whole is split in two (and in a special way three) sub-ontologies. The two ontologies are called Xesam Core and Xesam Convenience, besides these two there is a special collection of fields that does not apply to objects in general but only under special circumstances, these fields are defined in Xesam Virtual.

Xesam Core Ontology

This is a stable and generic ontology. It is intended to:

1. Implement a must-have field and category set which is most likely to be implemented by many Xesam services.
2. Provide "Mechanisms": Abstract structures and hooks for various use cases and functionality which will be provided by ontology extensions.

Examples of Mechanisms are: content relations, fingerprints, grouping, containers. This serves as guidelines for ontology extensions and helps to maintain a coherent and tightly coupled Core+Convenience+Extensions ontology, despite the unpredictable and ad-hoc nature of Extensions.

The important benefit is that applications aware of a particular Mechanism will be able to at least make some sense of all ontology extensions based on this Mechanism.

Xesam Convenience Ontology

The best way to describe this part of the ontology is "common extensions". Specifically:

1. Widely used and supported proprietary standards/formats/services. Including support for unpredictable and uncontrollable stuff into core is not wise.
2. Mappings to external ontologies/standards. Often there are several standards which overlap to a great degree. The overlap, the common part, goes to Core, and specifics go to Convenience. This way, Core implements the most important functionality, is not locked into any particular standard (along with apps using it), can be easily extended to support more standards.
3. User-friendly property names. Often it is desirable to provide alternate naming for properties like "title" for a specific content type or application area. While such renames are semantically irrelevant(don't convey any useful information), they may be more intuitive for users and software authors.
4. Potential additions to Xesam Core. Potential Core additions can be sandboxed and tested in Xesam Convenience.

Xesam Virtual Ontology

These fields are not real fields that can be expected to be treated like normal fields. A prime example is relevancyRating which only makes sense on an object given a query to do relevancy ranking against. Other notable virtual fields are contentCategory and sourceCategory - these can be specified as requested fields in the hit.fields session property of the Xesam Search Specification. The way to think about virtual fields is that they are not stored as ordinary fields but is somehow virtualized when requested in the right context. It is however up to the search engine how virtual fields are handled, some implementations might choose to treat them as first class fields, like any other.
