More specifically, the well-known object-oriented Unified Modeling Language (UML) is extended to capture the semantics of spatiotemporal data. The extension, Extended Spatiotemporal UML, maintains language clarity and simplicity by introducing a small base set of fundamental modeling constructs: spatial, temporal, and thematic. These constructs can then be combined and applied at attribute, attribute group, association, and\/or class levels of the object-oriented model; where the attribute group is an additional construct introduced for attributes with the same spatiotemporal properties. A formal functional specification of the semantic modeling constructs and their symbolic combinations is given and an example is used to illustrate the simplicity and flexibility of this approach.<\/p>","DOI":"10.4018\/jdm.2000100102","type":"journal-article","created":{"date-parts":[[2011,2,15]],"date-time":"2011-02-15T14:13:05Z","timestamp":1297779185000},"page":"14-27","source":"Crossref","is-referenced-by-count":24,"title":["Extended Spatiotemporal UML"],"prefix":"10.4018","volume":"11","author":[{"given":"Rosanne","family":"Price","sequence":"first","affiliation":[{"name":"Monash University, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nectaria","family":"Tryfona","sequence":"additional","affiliation":[{"name":"Aalborg University, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian S.","family":"Jensen","sequence":"additional","affiliation":[{"name":"Aalborg University, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","container-title":["Journal of Database Management"],"original-title":[],"language":"ng","link":[{"URL":"https:\/\/www.igi-global.com\/viewtitle.aspx?TitleId=3255","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T10:12:23Z","timestamp":1654078343000},"score":1,"resource":{"primary":{"URL":"https:\/\/services.igi-global.com\/resolvedoi\/resolve.aspx?doi=10.4018\/jdm.2000100102"}},"subtitle":["Motivations, Requirements and Constructs"],"short-title":[],"issued":{"date-parts":[[2000,10,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2000,10]]}},"URL":"https:\/\/doi.org\/10.4018\/jdm.2000100102","relation":{},"ISSN":["1063-8016","1533-8010"],"issn-type":[{"value":"1063-8016","type":"print"},{"value":"1533-8010","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,10,1]]}}}
