Categories are not meant to be constructed as such but to be projected from an ontology based knowledge base e.g. Topic-definitions made with Amaya or FMS Ontology. A category definition should have rdfs:label and possibly also rdfs:comment. A category may also have weight specified, which should be interpreted as weight of a triple _:c1 ogt:subCategoryOf _:c2, where _:c1 ogt:weight X. This interpretation is unambiguous since categories can have at most one super category. Top level categories should be sub categories of ogt:RootCategory. Implementation dependent identifier for category. If the category is a projection of some (domain ontology) resource the original resource is identified using this property. Super category. Only one super category allowed per Category. The root of the category hierarchy. Only one root category allowed per Category. Sub categories (ordered list). Values of this property are collections. Hits provides an estimation of the size of the result set with current restrictions. Number of hits related directly to this category. Number of unfiltered direct sub categories. TopicOf-property is used to define boomarks that the category is topic of. Position of category or bookmark in relation to the other categories/bookmarks of the same parent. Results for FacetSelector. Facet Ungrouped bookmark hits. CategoryConstraint is used to express category-based constraints and to select categories. Select or constraint category by its ogt:catid. If no category is provided the selector matches all (top) categories. If an instance specifies multiple values for ogt:category, the constraint is union of these. Constraint categories by of which resource they are projected from. Select or constraint categories by keyword. Select or constraint bookmarks by keyword. FacetSelector Query for Ontogator. Constraint-property is used to express bookmark-constraints of a view-based query. If multiple constraints are given the result is the intersection of these. Constraints are given as rdf:List e.g. using rdf:parseType="Collection". Accepted xml:lang for literals (e.g. rdfs:label). Filtering type: 1) NONE - no filtering, 2) PRE-QUERY - categories that have no bookmarks are filtered 3) POST-QUERY - categories with no bookmark hits are filtered Should the number of bookmark hits (ogt:bookmarkHits) be included in the result? Should the number of bookmark hits (ogt:bookmarkHits) be included in the path (ogt:hasRoot) of the result categories? Should the number of direct bookmark hits (ogt:directBookmarkHits) be included in the result? Should the number of ungrouped bookmark hits (ogt:remainder) be included in the result? Should the postion of sub categories and bookmarks (ogt:position) be included in the result? Should the number of sub category hits (ogt:subCategoryHits) be included in the result? Should the number of sub category hits (ogt:subCategoryHits) be included in the path (ogt:hasRoot) of the result categories? Property of a category to be included in the results. Property of a bookmark to be included in the results. Selector that matches all properties. To be used with incCategoryProperty and incBookmarkProperty. Should URIs of bookmarks related to a category be included in the category hierarchy? Default: false Should parents (ogt:hasRoot) of the selected category be included in the category hierarchy? In a sense this is the counter part to the ogt:incSubCategories property. Default: true Should topics of categories be included in the result (Bookmark#hasTopic): 1) NONE - no topics (default), 2) DIRECT - direct topics, 3) ALL - direct topics with paths (ogt:hasRoot). What sub categories, ALL, DIRECT or NONE, should be included in the result? Default: DIRECT Max bookmarks of a given category to be included in the result. This restriction is inherited, so if ogt:incSubCategories=ALL and ogt:maxBookmarks [ogt:limit = 4], no more than 4 bookmarks will be included in the result for each category in the specified hierarchy. Max sub categories of a given category to be included in the result. This restriction is inherited, so if ogt:incSubCategories=ALL and ogt:maxBookmarks [ogt:limit = "4"], no more than 4 sub categories will be included in the result for each category in the specified hierarchy. Number of bookmarks of the given category to be skipped. Number of sub categories of the given category to be skipped. Restriction specifies the target category and the limit. If no category is specified the target is the resulting Facet. Specifies the target category (ogt:catid) of a restriction. If no category is specified the target is the resulting Facet. Specifies the limit of a restriction. Negative values indicate no limit.
