Semantic wiki features
 Current properties
for the feature matrix in Semantic_Wiki_State_Of_The_Art#Wiki_Feature_Matrix
- Property:Has editing paradigm
- Property:SWikiFeat:AnnotationMechanism - the way annotations are made, e.g. manually or automatically
- Property:SWikiFeat:SubjectAttribution - what scope a semantic wiki supports for an annotation
- Property:SWikiFeat:SubjectGranularity - what lexical span a semantic wiki supports for an annotation. Use "document", "section", "sentence", "word".
- Property:SWikiFeat:RepresentationDistinction - whether a semantic wiki distinguishes between pages and concepts ("instance identification vs. reference").
- Property:SWikiFeat:TerminologyReuse - whether a semantic wiki supports ontologies ("interoperability").
- Property:SWikiFeat:ObjectType - the supported types of an annotation object. Use "literal", "page", "uri".
- Property:SWikiFeat:Context - whether a semantic wiki supports contexts for annotations (date of annotation, author of annotation, duration of validity, ...).
- Property:SWikiFeat:ImportInstances - whether a semantic wiki supports import of instances (e.g., import of RDF data).
- Property:SWikiFeat:ImportTerminology - whether a semantic wiki supports import of terminologies (e.g., import of RDFS ontologies).
- Property:SWikiFeat:Export - whether a semantic wiki supports exporting instance data (e.g., RDF export of annotations).
- Property:SWikiFeat:ClassModel - specifies “which way around” a class is defined, for wikis which maintain an implicit, or enforce an explicit, ontology.
 Proposed properties
 Informal and Formal
One criterion could be the structure of the content of the wiki:
- non-formal content enriched with semantic annotations
- formal (i.e. semantic) content, possibly enriched with non-formal annotations
The following properties (that use the term "annotation" in their definitions) make only sense for the first type of semantic wikis: Property:SWikiFeat:SubjectAttribution, Property:SWikiFeat:SubjectGranularity, Property:SWikiFeat:ObjectType, and Property:SWikiFeat:Context.
Similar proposal: does RDF annotate the wiki content or does the wiki content annotate the RDF (this is not mutually exclusive!).
 Level of Semantics
Another criterion could be the conceptual level where the semantics are applied:
- domain level (semantic information about the domain itself) - yes/no
- meta level (semantic information about authors, versions, etc.) - yes/no
- both (set both to yes)
 RDF persistence
How does the RDF get stored? Here I'm not sure how to classify it, because it involves things like named graphs or not, is RDF entered inside a page, is the page itself a subject or a named graph, etc. - Max: this sounds a lot like the SWikiFeat properties - Tobias: This should be formulated in a more general way. Who says that a semantic wiki has to store its data as RDF?
- I'd suggest to distinguish between RDF as the central, native storage format (as e.g. in Rhizome or Hyena), and RDF being extracted from pages in a different format when they are saved (as e.g. in Semantic MediaWiki or SWiM). --Christoph Lange 10:36, 12 November 2008 (UTC)
 Reasoning =
Which kind of reasoning the semantic wiki allows Which reasoning engine it implements What it does with deductions/conclusions/derived facts? Are they stored or forgotten? What they are? Are they RDF or other kind of format? ...
