<\/b><\/p>\nCURRENT RELEASE<\/b><\/p>\n
The current release of the IDM Tools comprises 3 tools, as shown by the figure below:<\/p>\n
Notice that for using the IDM Tools it is not necessary to install Enterprise Architect \u2013 these tools provide therefore free access to the Inspire Data Model.<\/p>\n
MOTIVATIONS<\/b><\/p>\n
The architecture of the IDM Tools is characterized by 2 main aspects:<\/p>\n
This architecture is motivated by considerations regarding the performance<\/i> of the services and the stability<\/i> of the data models. We believe that a WFS service must be supported by a full-fledged spatial DBMS in order to obtain acceptable performance, especially in presence of one or more of the following requirements:<\/p>\n Regarding the stability<\/i> of the Data Models, we believe that the UML model will be more stable than the XSDs which have been derived from it, since<\/p>\n A major investment which the INSPIRE Data producers will have to face in the next years will be the definition of the (semantic) transformation<\/i> from their Production Data Models to the INSPIRE Data Model. Since the structure of the INSPIRE Database is derived from the UML model, using the UML Model and the INSPIRE database as the target of these transformations will safeguard these investments from changes in the encodings. In fact, in this architecture different encodings can be produced without affecting the (semantic) transformations.<\/p>\n The IDM Tools are distributed with a preloaded INSPIRE UML Data Model; in the current release this preloaded Data Model has been derived from the official Inspire 2010-04-26_r937.eap<\/i> distribution. The derived model in .eap format can be downloaded from this site. The few transformations which have been applied to the INSPIRE Themes are due to the correction of some errors or to some requirements for GML encoding. The ISO package has been simplified and renamed as \u201cselected ISO TC211\u201d. A detailed description of these modifications is presented in the Preloaded Data Model<\/i> panel of the tool.<\/p>\n \u00a0FUTURE DEVELOPMENTS<\/strong><\/p>\n If the approach adopted by the IDM Tools will encounter the interest of stakeholders, we plan to develop it further in several directions:<\/p>\n WFS demo\u00a0<\/strong><\/p>\n As a demonstration of the functionalities of IDMT a DBS has been defined and the generated Script files have been used to create an INSPIRE DB and to install a WFS service at the following address:<\/p>\n http: wfs<\/em>.<\/em>spatialdbgroup <\/em>.<\/em>polimi.<\/em> it\/deegree-webservices-3<\/em>.<\/em>3.<\/em>9\/<\/em>services<\/em><\/p>\n The DBS definition is included in the IDMT_937 download. It has the following parameters:<\/p>\n The INSPIRE Database has been loaded with production data containing about 80,000 RoadLinks <\/em>and 30,000 RoadNodes<\/em>.<\/em><\/p>\n In order to use the service it is necessary to write the necessary queries and submit them with a Browser. Some example queries have been proposed as demonstrations in the following links (if a link starts but does not return a result, copy link in your browser and execute – we have tested Edge and Firefox):<\/p>\n http:\/\/wfs.spatialdbgroup.polimi.it\/deegree-webservices-3.3.9\/services?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&OUTPUTFORMAT=text%2Fxml%3B+subtype%3Dgml%2F2.1.2&TRAVERSEXLINKDEPTH=0&TypeName=RoadLink<\/span><\/a><\/p>\n http:\/\/wfs.spatialdbgroup.polimi.it\/deegree-webservices-3.3.9\/services?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&OUTPUTFORMAT=text%2Fxml%3B+subtype%3Dgml%2F3.2.1&TRAVERSEXLINKDEPTH=0&TypeName=RoadNode<\/a><\/span><\/p>\n http:\/\/wfs.spatialdbgroup.polimi.it\/deegree-webservices-3.3.9\/services?SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&OUTPUTFORMAT=text%2Fxml%3B+subtype%3Dgml%2F2.1.2&TRAVERSEXLINKDEPTH=0&BBOX=1686000,5026000,1705000,5035000&TypeName=RoadNode<\/a><\/span><\/p>\n Unfortunately, as far as we know current GIS clients are not able to deal with the complex INSPIRE GML encoding. However we have verified for example QGIS is able to read and display the RoadLinks and RoadNodes obtained from the above queries, although it loses all information of the associations between features.<\/p>\n \u00a0<\/em><\/p>\n DOWNLOAD<\/strong><\/p>\n\n\tIDMT_937_release1.0beta_2014-06-25.zip\t(34 downloads\t)\n<\/a>\n\n\n\t2010-04-26_r937revision1.zip\t(14 downloads\t)\n<\/a>\n\n","protected":false},"excerpt":{"rendered":" CURRENT RELEASE The current release of the IDM Tools comprises 3 tools, as shown by the figure below: the Model Browser, which provides a way of exploring the Conceptual Schema in a hypertext style that is different and complementary to reading UML diagrams;\u00a0 this is useful not only for non UML experts, but also for […]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page.php","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-43","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/pages\/43","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=43"}],"version-history":[{"count":39,"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/pages\/43\/revisions"}],"predecessor-version":[{"id":350,"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=\/wp\/v2\/pages\/43\/revisions\/350"}],"wp:attachment":[{"href":"https:\/\/spatialdbgroup.polimi.it\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=43"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}\n
