Purpose - The purpose of this research was to assess and compare the indexing and ranking of XML-based content objects containing MARCXML and XML-based Dublin Core (DCXML) metadata elements by general search engines (Google & Yahoo!), in comparative analytical study. Design/ methodology/approach – 100 XML content objects in two groups were analyzed: those with MARCXML elements (50 records) and those with DCXML (50 records) published in two websites (www.dcmixml.islamicdoc.org & www.marcxml.islamicdoc.org).The websites were then introduced to Google and Yahoo search engines. Findings – The indexing of metadata records and the difference between their indexing and ranking were examined using descriptive statistics and nonparametric Mann-Whitney U test. Findings show the visibility of content objects was possible by all their metadata elements. There was no significant difference between two groups' indexing, but difference was observed in case of ranking. Practical implications – The findings of this research can help search engine designers in the optimum use of metadata elements to improve their indexing and ranking process aimed to increasing availability, as well as, the Web content object providers for proper and efficient using of metadata systems. Originality/value – The research, is the first research that examines the interoperability between XML-based metadata and the Web search engines, and compares the MARC format and DCMI in a research approach.
