Files containing "skos:Concept" or "Concept" type "rdf:Description" are processed by this service.
A preliminary analysis of the resource is performed to determine:
| Check | Description |
|---|---|
| D-Id | Uniqueness of the identifier (URI) of a given concept. Two different concepts can't have the same identifier. |
| URI/IRI | An URI/IRI contains an illegal character (white space, apostrophe, double quotation mark, left bracket, right bracket, new line, tab character). |
| E-0 | Presence of an empty field (property). May interfere with the continuation of the control program. Can also prevent import into some terminology editors. |
| @-0 | Presence of an empty attribute. |
| R-A1 | Clash between semantic relations: the same concept is a related concept and a broader concept of the current concept. |
| R-FX1 | Reflexive hierarchical relation: a concept is its own broader concept. Such a situation represents a problem despite the fact that the SKOS specification doesn't state that "skos:broader" is a reflexive property, neither does it state the opposite. (see SKOS-Reference: skos:broader and reflexivity). |
| R-FX2 | Reflexive associative relation: a concept is its own related concept. The SKOS specification doesn't state that "skos:related" is a reflexive property, neither does it state the opposite. (see SKOS-Reference: skos:related and reflexivity). |
| R-31 | Clash between associative and hierarchical relations: if concept A has concept B as a narrower concept and concept C as a related concept, then C can not be a narrower concept of B because concept C can not be linked simultaneously to concept A by two disjoint relationships "skos:narrowerTransitive" and "skos:related". See details in SKOS-Reference: S27 integrity condition and in SKOS-Primer. |
| R-32 | Clash between associative and hierarchical relations: if concept A has concept B as a broader concept and concept C as a related concept, then C can not be a broader concept of B because concept C can not be linked simultaneously to concept A by two disjoint relationships "skos:broaderTransitive" and "skos:related". See details in SKOS-Reference: S27 integrity condition and in SKOS-Primer. |
| R-B3 | Clash between semantic relations: the same concept is a narrower concept and a broader concept of the current concept. Such a situation represents a problem despite being consistent with the SKOS data model. (see SKOS-Reference: Cycles in the hierarchical relation). |
| R-A2 | Clash between semantic relations: the same concept is a narrower concept and a related concept of the current concept. |
| R-NS | Non-symmetric associative link (skos:related). See SKOS-Reference: Class and Property Definitions. |
| R-0 | Relation (skos:related, skos:broader or skos:narrower) that targets a non-existent concept. |
| R-OR | Orphan concept: a concept that is not a top-concept, and which has neither broader nor narrower concepts. |
| CS-0 | Concept not linked to the concept scheme through "skos:inScheme" element. |
| CS-3 | Inconsistency at the level of the resource identifier (URI). The value of "rdf:resource" attribute in "skos:inScheme" element is different from the resource identifier. |
| LP-0 | Missing preferred label for one of the resource languages. |
| LP-N1 | More than one value preferred label per language tag. See SKOS-Reference: S14 integrity condition. |
| LP-LA1 | Preferred label / alternative label duplicate within the same concept. See SKOS-Reference: S13 integrity condition. |
| LP-LC1 | Preferred label / hidden label duplicate within the same concept. See SKOS-Reference: S13 integrity condition. |
| LP-LP2 | Same preferred label for two different concepts. |
| LP-LA2 | Preferred label / alternative label duplicate between two different concepts. |
| LP-LC2 | Preferred label / hidden label duplicate between two different concepts. |
| LA-LA1 | Alternative label duplicate within the same concept. |
| LA-LA2 | Same alternative label for two different concepts. |
| LA-LC1 | Alternative label / hidden label duplicate within the same concept. See SKOS-Reference: S13 integrity condition. |
| LA-LC2 | Alternative label / hidden label duplicate between two different concepts. |
| LC-LC1 | Hidden label duplicate within the same concept. |
| LC-LC2 | Same hidden label for two different concepts. |
