Digitalvideo Pattern

Source: ODP portal  ·  Published by: mklab.iti.gr  ·  Category: structural  ·  Domain: digital-media

The pattern intends to model digital video files, their components and other associated entities, such as codecs and containers.

What it answers

    1. What does a digital video file consist of? A digital video file usually consists of one or more streams. These streams are compressed using codecs (coder-decoder) and wrapped into a container. 2. What types of streams exist in a video file? Video streams, audio streams and subtitle streams. A video file has at least one video stream and may also have any number and any type of other streams. 3. What types of codecs exist? Video and audio codecs.

The pattern

The graph is the axioms the pattern asserts; nothing here is inferred. Drag to rearrange, scroll to zoom, and use the graph's own search box to find a term inside it.

Opens at level of detail 3: classes, individuals, properties and restrictions, without the literals. Raise it with the LOD control in the graph's own toolbar to see annotation values and anything a reasoner adds.

Should you use this one?
Size 31 classes, 27 properties, 288 axioms
Brings in 1 imported ontology, so adopting it adopts that too
Reasoning HermiT finds this pattern consistent, with no unsatisfiable class, and its worked example consistent with the pattern.

A situation it was written for. Some examples of instantiation of the DigitalVideo ODP are: 1. “The digital video is wrapped by an AVI container” 2. “The digital video has duration 22 minutes” 3. “The video stream is processed by the QuickTime codec” 4. “The audio stream has bitrate 256 kbit/s”

If a link does not open

ontologydesignpatterns.org, which publishes most of this library, does not currently answer over HTTPS, and its wiki redirects submission pages to its front page. The archived copy is there for exactly that reason. The ontology files themselves are still served over plain HTTP.

Terms it declares

The 58 classes and properties this pattern models, as the recommender scores them. Annotation properties and built-ins are excluded, because an annotation property is not modelling.

An example of it in use

The pattern says what may be asserted; this says it. The graph below is a small set of individuals that instantiate the classes above and are connected by its properties, so the shape the pattern describes is visible as data rather than as a schema.

Import this pattern into your own ontology from inside Protégé: OntoBoard → Reuse → Pattern library…, which hands it to Import terms… and writes the term list, the module, the import and the catalog entry the way ODK expects. See Working with ODK.
