| Abstract [eng] |
The usage of a classic content management system (CMS) has spread in the market of informational technologies because information is edited, authorized and published much easier in a multi-user environment. CMS is an ideal choice for large-scale organizations willing to control big amount of data from various resources. Usually this kind of information is presented in a web portal. However some weak points are found in a CMS as well. Particularly in organization of information, metadata support areas. Associations between various CMS objects such as blogs, wiki pages, information display elements aren’t supported enough. Similar to a file system many typical CMS store specific content objects in hierarchical catalogs. It is quite difficult to use this tree structure as information doesn’t fit there. Furthermore one association “type-instance” type does not define the purpose of information in the catalogs clearly. So this article describes how Topic Maps technology helps to avoid the limitations in organization of information used in a content management system. All the strengths of a classic CMS remain. Technology is built on top of CMS and lets the user describe the desired content in a topic map. Methodic explains Ontopia and Liferay integration, necessary configuration, ontology making and displaying Topic Maps information with portlets. Nowadays this open source approach is claimed to be one of the easiest and cheapest in building Topic Maps based web portals. |
