Abstract

The purpose of this research was to make exam the indexing and ranking of XML content objects containing Dublin Core and MARC 21 metadata elements in dynamic online information environments by general search engines and comparing them together in a comparative-analytical approach. 100 XML content objects in two groups were analyzed: those with DCXML elements and those with MARCXML elements were published in website http://www.marcdcmi.ir. from late Mordad 1388 till Khordad 1389. Then the website was introduced to Google and Yahoo search engines. Google search engine was able to retrieve fully all the content objects during the study period through their Dublin Core and MARC 21 metadata elements Yahoo search engine, however, did not respond at all. The indexing of metadata elements embedded in content objects in dynamic online information environments and different between indexing and ranking of them were examined. Findings showed all Dublin Core and MARC 21 metadata elements by Google search engine were indexed. And there was not observed difference between indexing and ranking DCXML and MARCXML metadata elements in dynamic online information environments by Google search engine.
