Preserving records in the cloud

Purpose – The purpose of this paper is to examine the characteristics of managing records in a cloud computing environment and compare these with existing archiving models, exemplified by the open archival information system (OAIS) reference model.Design/methodology/approach – The authors compare the functional entities in OAIS with a layered model of cloud computing, in which services are abstracted and shared between layers.Findings – It is concluded that there are a number of areas where OAIS does not integrate well with cloud computing systems. Based on the findings, a new layered model for a cloud archiving system is defined using the concepts and information types from the OAIS reference model. The proposed model allows the sharing of functionality and information objects by making them available as services to higher layers. The model covers the entire document lifecycle, making archive functionality such as preservation planning possible at an early stage and helping to simplify records transfer.R...

Archiving as a service: a model for the provision of shared archiving services using cloud computing

In this paper, we define some of the characteristics of archiving in a cloud computing environment. Based on these, we describe a model for a cloud archiving system using concepts and information types from the OAIS reference model. The proposed model allows the sharing of functionality and information objects by making these available as services to above layers. The model covers the entire document lifecycle, making archive functionality such as preservation planning possible at an early stage in the document lifecycle, helping to simplify records transfer. Finally, we use our model in a case study, using the records transfer process from Japanese government agencies to the National Archives of Japan as an example.

Identification of works of manga using LOD resources: an experimental FRBRization of bibliographic data of comic books

Manga -- a Japanese term meaning graphic novel or comic -- has been globally accepted. In Japan, there are a huge number of monographs and magazines of manga published. The work entity defined in Functional Requirements of Bibliographic Records (FRBR) is useful to identify and find manga. This paper examines how to identify manga works in a set of bibliographic records maintained by Kyoto International Manga Museum. It is known that authority data is useful to identify works from the bibliographic records. However, the authority data of manga is not rich, because manga has been recognized as a sub-culture resource and is generally not included in library collections. In this study, we used DBpedia, which is a large Linked Open Data (LOD) resource created from Wikipedia, to identify FRBR manga entities in bibliographic records. The results of this study show that using LOD resources is a reasonable way to identify works from bibliographic records. It also shows the accuracy and efficiency of work identification depending on the quality of the LOD resources used.

Developing an ontology for cloud-based archive systems

This paper presents a domain ontology for cloud archives, based in part on the PREMIS Editorial Committee ontology for the PREMIS Data Dictionary. Our ontologys design is based on a layered model of cloud computing where lower layers provide shared services to higher layers. It focuses on the submission of generic Submission Information Packages with PREMIS preservation metadata. An ontology is designed to define a common vocabulary for cloud archives, and define the roles and responsibilities for data creation and transfer, including the registration of cloud-based content creation systems. We define the classes, object properties, data properties and annotations necessary to describe the agents, objects, events and rights that comprise a cloud archive. We evaluated the ontology with a prototype system, using real-world examples of cloud systems, digital objects and metadata. We found that the ontology was able to describe the chosen components successfully, and that it improved metadata interoperability between content creating applications and the services providing preservation metadata.

A Metadata Schema Design Model and Support System Based on an Agile Development Model

A huge amount of metadata is being published from various communities, domains and countries on the Internet. Metadata schema designers need to design metadata schema for their applications considering the interoperability. Linked Open Data (LOD) is the concept and movement to facilitate the use of datasets across communities on the Internet. However, to publish metadata as LOD, metadata schema designers must be experts of LOD. Metadata schema design, which is similar to software design, requires design and evaluation cycles where the iterative prototyping of metadata is useful. Our goal is to help metadata schema designers design a metadata schema in an iterative prototyping process. In this paper, we describe a metadata schema design methodology based on the agile development model. And then, we propose a system to support the proposed methodology including a metadata-editing tool. Finally, we show some metadata schemas as examples.

A Metadata-Centric Approach to a Production and Browsing Platform of Manga

Manga has been very popular in Japan for many years and it is now gaining popularity worldwide. Given the new creation and display devices, the production and publication of manga is also changing. Once a manual art form, manga is becoming a digital art and so there are now emerging digital libraries of manga.This paper proposes a metadata-based platform to make manga production and browsing more efficient. We have designed metadata models to describe visual structure, bibliographic relationships and characters as intellectual entities, and so forth. The models are based on our Manga Metadata Framework, developed in our previous work, that defines the functional requirements of metadata for manga. This paper describes an authoring tool that for editing storyboards of manga while simultaneously creating metadata. This paper also shows a manga collection browser.

A metadata framework for cloud-based digital archives using METS with PREMIS

An increasing number of organizations are using cloud computing to create and store digital records. To ensure safe storage and long-term preservation, standards for metadata are needed. This paper proposes a metadata application profile for cloud archives. We use guidelines from the Singapore Framework for Dublin Core Application Profiles to define the functional requirements, domain model and description set profile that form the basis of the proposed application profile. In our profile, we use METS as a transmission and package format, extending it with metadata from the PREMIS data dictionary and Dublin Core Metadata Element Set. Using the proposed application profile, we create an example METS information package using predefined criteria. We find that the profile meets the functional requirements, and that it simplifies metadata provision for business systems, compared to systems that do not allow pre-registration.

A Manga Creator Support Tool Based on a Manga Production Process Model - Improving Productivity by Metadata

Manga is a Japanese style comic. Nowadays, production of manga in the digital environment is widely accepted since authoring/drawing tools on PC have become popular. However, the digitalization of manga production is only in the later stages of the whole production process. The goal of this research is to improve productivity of manga production using information technologies in the earlier stages of the process. A fundamental problem exists in information resource management in the production process, e.g., reuse of unused scenarios for a new content, revision of existing character image. In this paper we propose a manga production support tool which helps creators (re)use existing resource in the production process, e.g., annotations attached to design memos, communication history, and so on. The tool uses metadata for various resources used and created in the production process. This paper describes the background of the study and overviews the production support tool.

Bridging community resource gateways by linking community taxonomies

Many communities provide Web resource directories to help users find useful resources in the community. A typical example is a resource directory in a homepage of a local government. Crosswalk of the directories of neighboring communities is a crucial function for users to collect useful resources from the communities. However, an appropriate scheme bridging the community directories is required. This paper proposes a few mapping schemes to connect community directories and compares them by applying them to the resource directories of three local governments - Tokyo and Hokkaido in Japan and Chungcheongnam-do in Korea. The mapping schemes use National Diet Library Subject Heading (NDLSH) and/or Nippon Decimal Classification (NDC) as a switching language. Evaluation of the proposed schemes shows their advantages and limitations.
