The purpose of this study is to provide a model for implementing the linked data method in library systems (such as digital libraries and library catalogues), as well as to provide the components needed to perform this process. In this stage, in order to provide a practical example of converting metadata records based on linked data method, 40 metadata records from the total records of Shahnameh bibliographic family were purposefully selected from the Iran’s national library catalogue, and converted based on linked data method and finally it’s RDF graph was designed. In this study, after analyzing the structure of RDF language and connecting data in the linked data method, the steps of implementing this method in selected metadata records were explained. These steps include assigning URI; representing RDF model of bibliographic entities and relationships; converting examples of metadata records based on linked data method; providing RDF/XML code resulting from the conversion of one of the metadata records based on the linked data method; and finally creating an RDF graph. The links established in the RDF/XML syntax are richer, more accurate, more comprehensive, and more structured than current formats, and the use of linked data method allows for the coverage of a variety of bibliographic relationships between related works. Therefore, it seems that the application of linked data method can have significant effects on the process of describing and displaying relationships and links between bibliographic metadata in library systems.

INTRUDUCTION: The aim of this study is to find out the relationship designators in the metadata records of the National Library and Archives of Iran (NLAI), based on the Resource Description and Access (RDA) standard.
In this study, the content analysis method was used. The study population included metadata records for books in NLAI for four bibliographic families including Quran, Nahj al-Balagha, Shahnameh, and Masnavi (with a total of 28213 records) that were accessible through the NLAI OPAC, named RASA. In this study, the data gathering methods were structured systematic observation and documentary approach. A checklist is used for data gathering, and a matrix is used to display the analyzed data.
FINDINGS:The results of the study showed that among the 544 relationship designators in appendices I, J, & M in RDA Toolkit (that includes 150 designators in appendix I, 346 designators in appendix J, and 48 designators in appendix M), 62 designators for appendix I, 175 designators for appendix J, and 48 designators for appendix M (In total, 285 designators) were detected in the selected NLAI metadata records. No relationship designators were detected in the selected NLAI metadata records in appendix I, for relationship designators related to "Publishers" and "Distributors" (in the Manifestation level), and in appendix J, for "Accompanying Manifestation Relationships". But other types of relationships were found to be existed.
In appendix I, the section of designators for "Publishers" and "Distributors" includes designators for non-book content objects (e.g. movies, radio & television programs, and so on) and don’t fit in the study population of this research, which are records of books. Therefore, it can be concluded that the study population has covered the variety of relationships provided for books in appendix I. The results also indicate the complete coverage of the relationship designators presented in Appendix M (subject relationships). In contrast, the study population does not provide a complete coverage of the relationships presented in appendix J (for "Accompanying Manifestation Relationships"). Finally, some of the limitations and drawbacks in the metadata records of the NLAI OPAC are mentioned.

The aim of this study is to find out the bibliographic relationships between the metadata records in the National Library and Archives of Iran (NLAI) according to FRBR model, in order to represent the knowledge network of Iranian-Islamic publications. To achieve this objective, content analysis method was used. The study population includes metadata records for books in NLAI for four bibliographic families including The Quran, Nahj al-Balagha, Shahnameh, and Masnavi (a total of 28213 records) that were accessible through the NLAI OPAC. In this study, the data gathering methods were structured (systematic) observation and documentary method. A checklist is used for data gathering, and a matrix is used to display the analyzed data. The results of the study showed that all relationship types of the Functional Requirements for Bibliographic Records (FRBR) model, except the “arrangement (music)” relationship from the section “Expression-to-Expression Relationships: between expressions of the same work”, were found in metadata records. Since the “arrangement (music)” relationship is used only for musical objects, it can be concluded that NLAI encompasses the entire range of the FRBR relationship types that provided for books. The results of this study can be useful to implement FRBR model in Iranian libraries, and also to design NLAI metadata ontology model and create and publish the NLAI ataset based on linked data method.
