This article identifies the use of a variety of standard formats for storing video, text, multimedia and audio resources in the digital collections of 20 selected national libraries around the world. This study is applied, based on descriptive-analytical method. For data collection we used researcher-made questionnaire. After collecting data, a variety of descriptive statistical techniques such as frequency distribution and frequency percentage and Chi-square test were used to analysis the dat. Based on the results, it was found that image sources were used in all studied collections and cultural objects were less popular with a share of 41%, for TIFF image sources (94%); HTML and XML text sources (75%); WAV audio sources (65%) and AVI multimedia sources (65%) were the most common.

The purpose of this study is systematic reviewing of organizing metadata standards to find the status of researches in digital libraries. The research attempted to categorize them in terms of the functional area and role that they play in digital libraries. By identifying the statue studded standards, it is possible to determine the functional place of other standards that expanded in the digital library area and are functionally similar to covered standards in this research. In this way, systematic review was used for study. By searching the databases, finally 42 research sources were selected for final review. Findings showed that the organizing standards, based on they role in digital library, could be categorized in seven sections (include Resource description, Resource structure determination, Resource management, Resource content organization, Local format definition in digital library database management system, Semantic context and interoperability). Then, a set of standards in each area were identified (50 standards in total). The results finally showed that MARC with 60.5%, DC with 44.7% and OAI and MODS with 42.1% were the most known standards. Audio-MD, VIDEO-MD with 5.3% also were the most unknown.
