This study aims to design folk song metadata based on the OAIS reference model for the folk songs' preservation and permanent use. Thus, the folk songs' general characteristics were investigated by researching literature and related technical standards. The type of records, the methods and standards for long-term storage of records, OAIS reference models, and each package's metadata elements were identified through opinions from the popular songs' creators and researchers. The results awere that first, folk songs were created for social transformation, serving as a cultural heritage different from popular songs given their noncommercial quality. Second, the types of folk song records were identified, and the long-term preservation system suitable for the types of records was based on the OAIS reference model. Third, the metadata were edited, and the OIS reference model was applied such that respect was given to the folk songs' characteristics, context, and original order. Fourth and last, information package metadata elements matching the folk songs' records were derived and applied to the representative Korean folk song, "The March for Being."

This study aimed to suggest metadata elements for online reference resource systems based on users' perceptions. We surveyed librarians in four types of libraries, asking them indicate the need for each of 17 metadata elements. The survey results were compared to the current data input rates of the system, which has been operating for the past two years. Based on both the respondent data and current data input rates, we suggested that title, description, subject, creator, type, identifier, language, coverage, location, and tag elements must be included in the system as the metadata elements for online reference resources. n addition, the input rates of creator and copyright were 20.20% and 18.30%, respectively, but the respondents answered that these items were needed 82.15% and 82.77%, respectively. Therefore, these two items are necessary as metadata elements. On the other hand, the data input rates of type, source, date, relation, and contribution were less than 3%, but almost 70% of respondents answered that all these items were needed. So further research should be performed to determine whether or not these items are needed for online reference resource systems.

This study is to develope the structures and the elements of the metadata for harvesting, management and preservation of a valuable web resources in the web archiving. For this study, we investigated the available metadata in the web archiving and surveyed the requirements of web archiving process. And we analyzed the characteristics of web resources. Also, this study was used a based on the ISO 14721 OAIS Reference Model. Finally, to share the metadata elements among the web archiving system, this study considered the interoperability for the exchange of the metadata. Based on the result, this study designed four structures of the metadata and defined the 28 core metadata elements for the web archiving.

Digital information resource requires detailed metadata to ensure its long-term preservation and accessibility for future generations. This paper illuminated the characteristics of digital information resources, the concept of digital preservation and the necessity of metadata for long-term preservation of digital information resources. And this paper examined the 16 elements of RLG metadata for preserving digital information and the Reference Model for an Open Archival Information System(OATS) to support the interoperability of digital archiving. And then this study investigated concretely element sets of the preservation metadata for digital information resources in the Cedars and OCLC/RLG embodied within the OAIS framework. As result of the study, the paper suggested basic plan required to provide preservation metadata elements to preserve digital information resources in Korea.

For long-term preservation of electronic records, the information on the whole processes of management from the time of creation of the electronic information should be captured and managed together. Such information is supported by preservation metadata thus the implementation of preservation metadata is important for preservation of electronic records maintaining the record-ness. Preservation metadata is the information that supports the process of digital preservation and functions th maintain long-term viability, renderability, understandability, authenticity and identity of digital resources. Preservation metadata should be developed applying the international standard Reference Model for an Open Archival Information System(OAIS) to have international interoperability for exchange and reuse. Initial international preservation metadata schemas were developed standardizing the OAIS Reference Model. But the preservation metadata schema of Victorian Electronic Records Strategy(VERS) and recently published Data Dictionary of PREMIS Working Group were developed in advanced types that are different from the existing framework. Those were advanced th practical ones from conceptual one. Comparing these two cases, proposed the elements of integral preservation metadata for long-term preservation of electronic records. This thesis has the significance that it has suggested the direction for future development of the elements of preservation metadata by setting the past discussions related to preservation metadata in order and proposing integral preservation metadata elements for long-term preservation of electronic records.

Bibliographic metadata can help researchers effectively utilize essential publications that they need and grasp academic trends of their own fields. With the manual creation of the metadata costly and time-consuming. it is nontrivial to effectively automatize the metadata construction using rule-based methods due to the immoderate variety of the article forms and styles according to publishers and academic societies. Therefore, this study proposes a two-step extraction process based on rules and deep neural networks for generating bibliographic metadata of scientific articlles to overcome the difficulties above. The extraction target areas in articles were identified by using a deep neural network-based model, and then the details in the areas were analyzed and sub-divided into relevant metadata elements. IThe proposed model also includes a model for generating reference summary information, which is able to separate the end of the text and the starting point of a reference, and to extract individual references by essential rule set, and to identify all the bibliographic items in each reference by a deep neural network. In addition, in order to confirm the possibility of a model that generates the bibliographic information of academic papers without pre- and post-processing, we conducted an in-depth comparative experiment with various settings and configurations. As a result of the experiment, the method proposed in this paper showed higher performance.

Social network service is defined as an online service or communication service based on social relations among people applied the concept of social network. Social collaborative service included in social network service is characterized by the new value of modified content or recreated content made through collaborative creation process between members of the group. It has the remarkable merits such as sharing and collaboration. But, at the same time, it has the latent problems such as content reuse or copy that is not allowed for members to use. It has been emerged that UCC which is a typical example of recreated or modified content has the copyright issues in both creation and publishing step. To resolve this matter, we don't have many appropriate methods except CCL so far. So, in this paper, we define the problem and implement the UCC metadata manager to control metadata reflecting the feature of UCC. We draw the reference metadata element to identify original content utilized re-creation process. After that we define the R.Metadata Loader module based on the use case. Finally, the proposed UCC metadata manager provides the information of referenced content and lets us to identify the relationship between reference contents. So as to implement prototype, we use Kaltura which is CMS using open source and obtain functional extensibility of metadata manager by using open API.

As the amount of information increases explosively with the development of society, the need for a digital archive has emerged in order to maintain information efficiently. There is a current standard of digital archive is OAIS(Open Archival Information System) reference model. OAIS reference model is mainly interested in long-term preservation and concerned about comprehensive content. This paper propose digital archive workflow that is used not only for long-term preservation but also for the efficient utilization with the image data. The OAIS reference model and the metadata standard should be added surge information to build a digital archive. Therefore we propose metadata model should be managed based on multi-level classes not only for effective digital image archive but also for utilization.
