The aim of this research was to examine the use of data island method for creating metadata records based on DCXML, MARCXML, and MARC21with indexability and visibility of element tag names in the Web search engines environment. 600 metadata records were developed in two groups (300 XML-based records as the control group with the normal structure, and 300 HTML-based records in an experimental group with special structure embedded in the tag of HTML based on the data island strategy). These records were analyzed through an experimental approach. The records of these two groups were published on two independent websites and were introduced to Google and Yahoo! search engines for indexing. Findings show that all the element tag names of the metadata records created based on the data island method relating to the experimental group indexed by Google and Yahoo! were visible in the search results. But the element tag names in the control group’s metadata records were not indexed by the search engines. Based on this study, it is possible to retrieve the metadata records by their element tag name in search engines. But the records of the control group are accessible by the element values only. The research suggests some patterns to metadata creators and end users.

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.

This article, after introducing the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH), tries to show how this protocol can be useful for creating union catalogues of archival records. The overall objective of OAI-PMH is to facilitate the transfer of information as metadata in network environments. It does so using Dublin Core metadata elements, Extensible Markup Language (XML), and Hypertext Transfer Protocol (HTTP). This article defines metadata, introduces the metadata elements of Dublin Core and shows the proposed structure of metadata record based on the proposed pattern in the XML template. It also gives some explanations about the six requests for metadata using HTTP protocol and shows that how record owners can play the role of data providers and record preserving bodies can act as service providers. Finally, the main and subsidiary benefits of using this protocol have been pointed out.

The purpose of the research was to make clear the concepts, challenges, and current approaches of the interoperability between metadata systems and the web search engines. The present research was a conceptual research carried out done based on an analytical-critical approach with emphasizing on the related researches. For reaching this purpose, meanwhile dividing the area's approaches into four approaches, first in each section, presents a conceptual discussion, then related researches have been reviewed, and finally, the challenges and approaches analyzed. The findings show there are four approaches in that area. And, the syntax of implementing metadata systems affects on their usability in the various information contexts. As well as, affects on indexability, retrieability, visibility, and ranking of the content objects in the Web search engines, The Web search engines are compatible with HTML's tags and metatags. But the limitations of HTML's tags and meta tags, and its function for display only, decrease its performance in organizing the content objects. But XML due to its extensible structure improves the interoperability between metadata systems and the Web search engines.

Dialectology studies a dialect scientifically along with its geographical distribution.Each dialect is a language; and to study a dialect various linguistic analyses are required.This property makes the study of a language a little long in terms of time.Collecting dialectical data is very time consuming and required a lot of effort.Raw data is not much usable in dialectology and it is required to add linguistic analyses to the data in the framework of structural linguistic analysis.Using a computer as a research tool causes to prepare the data in a specific structure.The main contribution of the current paper is proposing a standard to organize dialectic data and information.This standard contains the dialectic data, its relevant meta-data, and the linguistic information related to the analysis of this data.The meta-data and linguistic information are organized in the XML tree structure.This data structure is highly portable and it can be easily read into a database.

The aim of this research was to examine the indexing quality and ranking of XML content objects containing MARC21 and Dublin Core metadata elements by major search engines, and comparing them together in an experimental study. 100 XML content objects in two groups were analyzed: those with MARCXML elements and those with DCXML ones published in two websites (www.dcmixml.islamicdoc.com & www.marcxml.islamicdoc.com). The websites introduced to the selected search engines, Google and Yahoo. The indexing quality of metadata records embedded in content objects using descriptive statistics, and the difference between indexing and ranking of them using nonparametric mann-whitney U test were examined. Findings show that the visibility of content objects was possible by all their metadata elements. There was no significant difference between the two group's indexing quality but observed in case of ranking.

The aim of this research was to find out the status of indexing and ranking MARCXML and DCXML metadata records based on the linking approach by Web search engines. 100 XML-based metadata records in two groups (50 DCXML metadata records in the first group and 50 MARCXML metadata records in the second group were analyzed through a comparative-analytical approach. The records were published on an independent website (http://www.aghaabedi.com), and were introduced to Google and Yahoo! search engines directly. Then using search strategies, the indexability and ranking of the published metadata records were examined. findings show all the metadata element values were indexed by Google and Yahoo!, and all the metadata records were ranked in the search results. Based on the research, all the metadata records are retrievable in Web search engines environment by the element values. There was no significant difference between two groups’ indexing and ranking. Implementing metadata records in XML syntax improves the indexability of them. This feature helps users to retrieve the content objects by Web search engines, but does not affect the ranking of the metadata records and the DCXML and MARCXML records were ranked equally.

This research was conducted to examine the effect of discarding XML declaration and changing the file extension on increasing the index ability and visibility of the element tag names of metadata records based on DCXML, MARCXML, and MODS in the Web search engines environment.
Two groups of metadata records (300 XML-based records as the control group with the normal structure, and 300 XML-based records without XML declaration and with the extension according to the name of related metadata standard in an experimental group) were analyzed through the experimental approach. Two independent websites assigned to each studied group, and they were introduced to Google and Yahoo search engines. Subsequently, using element-based search strategies, the index ability and visibility of the published metadata records on those websites were examined.
Findings: Findings showed that Google and Yahoo indexed all the elements of tagged names of the metadata records relating to the experimental group indexes, and presented them in their search results. But the elements of tagged names in the control group’s metadata records were not indexed by the search engines.
Based on this study, it is possible to retrieve the experimental group's metadata records by their element of tagged names in the search engines. But the records of the control group are accessible by the values of the element only. In the end, , some patterns were suggested to the metadata creators and the search engine developers.

the purpose of this research is to determine the compatibility of Resource Description and Access (RDA) rules related recordings of attributes of first and second groups of FRBR with Metadata Object Description Schema (MODS) the research population includes primary and secondary parts, and attributes of the Metadata Object Description Schema (MODS) on the one hand; and Resource Description and Access rules related recording of attributes of first and second groups of FRBR on the other hand. The research used comparative method to gather needed data on both aspects of the study, to check how are compatible these two aspects, and to produce eXtensible Markup Language (XML) tags for providing descriptive information of different resources according to the Resource Description and Access (RDA). in general, 440 rules were identified and analyzed from the current RDA chapters 2-11. 440 MODS–oriented tags were compatible with RDA rules. The present research shows that all of the RDA rules related recording of attributes of first and second groups of FRBR are compatible with MODS and equivalents could be found in MODS for information extracted from the RDA rules. To make compatible RDA rules with MODS, more than one primary part should be used in some of the rules; especially those that are usually manipulated for providing access points to different entities. out of the 20 primary parts of MODS, 16 were used in this research. These 16 parts were selected according to the first and second entity groups in FRBR. Findings indicated that there is a full compatibility between RDA rules and MODS; and one would either be able to describe the information of a given resource in RDA or MODS. Findings are in fact a mixture of primary and secondary parts, specifications and values of RDA compatibilized with MODS. They would also be able to act as a model for describing Persian resources.. Finally, the research shows examples of Persian records randomly retrieved from the national bibliography which have been described according to the recommended tags.

The development of complex software systems Wants models that non-functional requirements evaluation of systems do in the development process, especially in the early stages. Architecture evaluation is done in different ways Hence need to have a way to integrate non-functional requirements. This Paper, MVC design pattern show in the form of framework based on extensible markup language for evaluating performance non-functional requirements. This framework is based on Petri nets that help can be it provided the MVC design pattern. The current study compared with RelatedWork provides Take advantage of Extensible Markup Language,   To address non-functional requirements and will be drawn an executable model of the application.
