Music Information Retrieval (MIR) involves searching and organizing large collection of music information and requires a conceptual model for bibliographic relationships in various works. Bibliographic relationships define all relationships involved in cataloging bibliographic units. The purpose of this research is to study the characteristics of Iranian musical bibliographic records by analyzing their work-to-work relationships based on the Functional Requirements for Bibliographic Records (FRBR) model.

This study uses a quantitative approach and practical method in order to analysis bibliographic data. The research method is a descriptive survey. The statistical population includes all Iranian musical bibliographic records available in the OPAC of the National Library of Iran from 2011 to 2018 and includes 1367 records for musical works. Data gathering method includes structural observation and documentary method and data gathering tool is a check list. The bibliographic relationships among records are studied according to the table of work-to-work relationships noted in IFLA final report.

Of 1367 bibliographic records that belong to musical works, 320 (23/4%) have work-to-work bibliographic relationships. The highest percentage of work-to-work relationships consists of 304 (95%) adaptive relationships and 16 (5%) complementary relationships. Other work-to-work relationships such as supplement, succession, transformation, summarization and imitation ones do not exist among Iranian musical works. The distribution of relationships in referential and autonomous works consists of adaptation with 301 (94.69%), incidental music with 16 (5%), fantasy with 2 (0.62%) and variation with 1 (0.31%). The rest of the sub-relationships types, as well as main relationships are not seen among the musical works.

The high percentage of Iranian musical works recorded in the National Library of Iran includes traditional Persian music and principal musical modal systems (Dastgah) which, cannot be traced in the features of the international music. Therefore, sub-relationships such as variation, harmonization, cadenza, libretto (operas), etc., as defined in the IFLA report for bibliographic relationships of a work were not mentioned among such musical compositions based on Dastgah music. Most of Iranian musical works are adapted from poetry and lyrics. The distribution of bibliographic relationships among Iranian musical works is only in two adaptation and complement types. Sub-relationships like Cadenza, Libretto, Choreography, Variation, Harmonization and Fantasy, unique to musical works does not exist in most of existing Iranian musical works. Hence, considering the significant difference between Iranian musical works and international musical works, using of FRBR for Iranian musical works in work-to-work relationships is not economically benefit.

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.

The purpose of this paper is to analyze and identify the different types of bibliographic relationships and vocabularies represented in Persian literary families. This could help cataloguers and catalogue designers to do more meaningful information organization.
Research population included the bibliographic records of four literary families: Shahnameh, Masnavi, Hafez's Divan, and Saadi's Gulistan. Content analysis was applied to identify and analyze the vocabularies representing bibliographic relationships in these families’ bibliographic records being stored in the OPAC of the National Library of Iran. Based on the systematic sampling method, 351 records for Shahnameh, 346 records for Hafez's Divan, 320 records for Masnavi, and 305 records for Saadi's Gulistan were selected.
Findings: 63.41% of the records had at least one type of relationship from which most of them were derivative. The most frequent type of the relationships were abridgement”, revision, based on specific expression, ommentary”, and adaptation. Also, the pattern and the frequency of the relationships in all families were different. Most of the relationships were seen with different types of vocabularies. In order to better display the information in library OPACs, the categorized file of vocabularies representing the bibliographic relationships in OPACs can be developed and implemented. Also, the paper introduces the most frequent vocabularies as a means for automatically managing the records related to the bibliographic families and enhancing the vocabulary control in RDA and Uniform Titles.

Functional Requirements for Bibliographic Records (FRBR) is a conceptual entity–relationship model developed by the International Federation of Library Associations and Institutions (IFLA) and is from a user’s perspective and based on his needs. Relation types between entities are mentioned in the FRBR pattern but the elements that link related resources and make relationships are not identified. Therefore, this study determines relationship-making elements in IRANMARC based on relationships present in the first group entities of Functional Requirements of Bibliographic Records pattern.
This study is a comparative research in an analytical perspective and is conducted based on library studies. All relation types present in FRBR first group entities are extracted and translated from FRBR manual, part 5 and RDA, J addition. Then they were matched with data elements of IRANMARC through four methods of identifiers, documented access points, structured and unstructured descriptions and the results are represented in tables.
by matching all the data elements of IRANMARC 10 blocks with the relation types between FRBR first group entities in RDA, J addition, it was clear that 44 element in IRANMARC are match able with relation types in the level of work, 41 element in IRANMARC are match able with relation types in the level of expression, 17 elements are match able with relation types in the level of manifestation, and 10 elements are match able with relation types in the level of item.
Our findings show that there is at least one relational field in UNIMARC format for representing various bibliographic relation types. Data elements of IRANMARC 4xx block are to a great extent matched with bibliographic relationship titles in FRBR, and present relations between related works can be represented by these relational fields.

This study aims to identify the descriptive data and bibliographic relationships applied in the bibliographic records of digital libraries of Iran. The accordance rate of these descriptive data, which have been created according to Anglo American Cataloging Rules, is measured by Resource Description and Access (RDA) standard. Design/Methodology/Approach: The present study enjoys practical descriptive-survey method. The method of data collection is observation and analysis. The data gathering tools consist of 3 checklists. This study identifies that the elements associated with the areas like "the artist title and description", "the type of resource ", "the publication areas" and "the Physical description area" are mostly applied among the 8 bibliographic description areas. The survey on bibliographic relationships applied in the bibliographic records of digital libraries show that the Equivalence Relationship and Derivative Relationship are widely used and the application of Accompanying Relationship and Sequential Relationship are at a minimum. Comparing the characteristics of the entities of “work, expression, manifestation and item” based on Resource Description and Access (RDA) Standard with the descriptive data present in bibliographic records in digital libraries prove that most of the characteristics defined in the entities of “work, expression and item” are not available in the mentioned records, but about the characteristics of the entity of “manifestation” a little accordance with the mentioned records is available. Considering the fact that each of the characteristics of the entities of Resource Description and Access (RDA) standard is defined based on the requirements defined in its 2 basic conceptual models i.e. Functional Requirements for Bibliographic Records (FRBR) and Functional Requirements for Authority Data (FRAD) and each of them can cover some of these requirements, the concept and function of each required data element needs to be specificallydefined and classified, therefore they can be properly applied in bibliographical records.

The purpose of this paper was to identify the bibliographic relationships in Persian bibliographic universe and fields necessary to illustrate them. Research methodology was survey and conducted through a research-made check list. Results indicated that there is high percentage of bibliographic relationships in bibliographic universe. Also, 42.85% of the relational fields applied in illustrating the identified bibliographic relationships. The result of this paper showed that some of the relational fields specially have used for illustrating of bibliographic relationships in Persian bibliographic universe.

This study was conducted to investigate the bibliographic relationships in the MARC and it’s consistency with the FRBR model. With establishing the necessary relations between bibliographic records, users will retrieve their necessary information faster and more easily. It is important to make a good communication in existing bibliographic records to help users to find what they need. This study’s purpose was to define the relationships between bibliographic records in the National Library's OPAC database and the study’s method was descriptive content analysis approach. In this study, the online catalog (OPAC) National Library of Iran has been used to collect information. All records with the mentioned criteria listed in the final report of the IFLA bibliographic relations about the first group entities in FRBR model and RDA rules has been implemented and analyzed. According to this study, if software has been developed in which the data transferring was based on the conceptual model and the MARC’s data that already exists in the National Library's bibliographic database, these relationships will not be transferable. Withal, in this study the relationships on consistent FRBR and MARC concluded with an intelligent mind and the machine is unable to detect them. The results of this study showed that the relations which conveyed from MARC to FRBR, was about 47/70 percent of the MARC fields, in other hand by FRBR to MARC with the use of all intelligent efforts, and diagnosis of MARC relationships, only 31/38 percent of the relations can be covered through the MARC. But based on real data and usable fields in Boostan-e-Saadi with MARC pattern, records on the National Library of Iran showed that the results reduced to 16/95 percent.
