has processing error text: [2,"smw-datavalue-wikipage-invalid-title","An n-ary relationship should be used to address any of the following situations: \n(a) a binary relationship that really needs a further argument. For example, to represent the distance between two places.\n\n(b) two binary relationships that always go together and should be represented as one n-ary relation. For example, to represent the value of an observation (e.g. temperature in a patient) and its trend.\n\n(c) a relationship that is really amongst several things. For example, to represent the spatial location of a person in a given point of time.\n\nOn the one hand, the motivation of this pattern is to express the inverse relationship of an n-ary relation where there are distinguished participants. This means that the relationship exists mainly between two entities and the rest of entities involved in the relationship can be considered as additional arguments. This situation can also mean that there is a single individual standing out as the subject or the \"owner\" of the relation. \n\nOn the other hand, the motivation is to provide a shorcut for queries that involve the distinguished participants in the n-ary relationship. \n\nThis pattern is inspired on the third consideration shown in http:\/\/www.w3.org\/TR\/swbp-n-aryRelations\/#choosingPattern1or2. The difference in our case is that there are at least two distinguished participants in the relationship. Therefore, this pattern could be considered as an extension of the third consideration shown in http:\/\/www.w3.org\/TR\/swbp-n-aryRelations.\/#choosingPattern1or2 applied to the use case of n-ary relationships described in http:\/\/www.w3.org\/TR\/swbp-n-aryRelations\/#useCase1."]
