Framework for photographic archives interoperability

Integrated library system is a part of institutional digital repository in modern library environment. Some popular open source software has been used in this regard. Development of an integrated institutional digital repository system is possible on the basis of global recommendations and local requirements of all libraries. OAI-PMH in Koha can be displayed in two ways such as sets and metadata with multilingual documents. The benefits of this study is harvest the records from the other library and it can make the union catalogue for anybody can be accessed from this integrated OAI-PMH harvesting framework available in Koha OPAC. This is the web 2.0 concept to achieve the multiple tasks of different library resources such as books, journals, magazines, reference books etc. for the better management and retrieval of resources among the library users. Digital resources are increasing in this modern age due to exponential growth of technological impact and its peripherals. IDRs will additionally include digital materials that subsist outside the physical and administrative bounds of any one digital library. IDRs will include all the processes and accommodations that are the backbone and nervous system of libraries. The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is a very high performance mechanism for client server architecture in repository interoperability. Broadly it can be classified in two ways such as data provider and service provider. Data Provider can access the structured standards global metadata by using OAI-PMH tool. Development of web services through Koha can be achieved in four ways such as OAI-PMH, ILS-DI, Z39.50, and OPAC tag cloud. On the other hand service providers then easily harvest the metadata through a set of six verbs of OAI-PMH based URL. Requests for data can be based on a timestamp range, and can be restricted to named sets defined by the provider. Data providers can only manage the XML based Dublin Core metadata format. It is possible to design and develop an integrated institutional digital repository in different ways. In this research paper highlights and displays the important interface such as OAI-PMH, ILS-DI, Z39.50, and tag cloud and all the interfaces have been displayed in Koha OPAC. The whole tasks have been developed and performed in Ubuntu operating system for easy installation, configuration, and retrieving of library resources among the users.

Motivated by preservation and resource discovery, we examine how digital resources, and not just metadata about resources, can be harvested using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). We review and critique existing techniques for identifying and gathering digital resources using metadata harvested through the OAI-PMH. We introduce an alternative solution that builds on the introduction of complex object formats that provide a more accurate way to describe digital resources. We argue that the use of complex object formats as OAI-PMH metadata formats results in a reliable and attractive approach for incremental harvesting of resources using the OAI-PMH.

Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) provides an application-independent interoperability framework based on metadata harvesting. It is an effective way of sharing metadata between gateway services. The chapter gives an overview of Open Archives Initiative and underscores development, structure, and basic working of OAIPMH for harvesting procedures. It also traces the emerging trends in the use of Open Archive Initiative-Protocol for Metadata Harvesting (OAI-PMH) by open access repositories to support interoperability among globally distributed information systems. The study was carried out by consulting the database of Directory of Open Access Repositories (OpenDOAR), which is an authoritative directory of academic open access repositories. The study observed growth in the use and application of OAI-PMH protocol by OA repositories at a global level. Growth in the number of OAI-PMH complaint repositories provides an ample justification for its distinction among varied protocols to be utilized for resource sharing in knowledge society. However, developing and underdeveloped nations need to be made aware of the benefits of utilizing the harvesting capabilities of this protocol. The study provides an opportunity to understand the astounding growing trends in the use of the protocol in different setups.

The Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) was first released in January 2001. Since that time, the protocol has been adopted by a broad community and become the focus of a number of research and implementation projects. We describe the various activities building on the OAI-PMH since its first release. We then describe the activities and decisions leading up to the release of a stable Version 2 of the OAI-PMH. Finally, we describe the key features of OAI-PMH Version 2.KeywordsDigital LibraryData ProviderSimple Object Access ProtocolRegistration ServiceMellon FoundationThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

PurposeTo make CDS/ISIS databases OAI‐compliant.Design/methodology/approachOne of the biggest obstacles for information dissemination to a user community is that many digital libraries or bibliographic databases use heterogeneous technologies that inhibit interoperability. The Open Archives Initiative (OAI) addresses interoperability by using a framework to facilitate the discovery of content stored in distributed archives or bibliographic databases through the use of the OAI Protocol for Metadata Harvesting (OAI‐PMH). Though the OAI‐PMH is becoming the de facto standard, many of the legacy databases or bibliographic systems, for various reasons, are not OAI‐compliant. CDS/ISIS is one such database system. In this paper, we discuss the static repository (SR) approach to make CDS/ISIS databases OAI‐compliant. The records from a CDS/ISIS database are exported onto a file and the exported records are then converted to the SR XML file format. The SR file is made OAI‐compliant either by ingesting it into the Kepler Archivelet or through the intermediation of a static repository gateway (SRG).FindingsThe SR is a simple approach for making bibliographic records contained in non‐OAI‐compliant systems, OAI‐compliant.Research limitations/implicationsThe SR approach is meant for records, which are relatively static. If the OAI‐compliance is achieved through the SRG, then the number of records contained in a SR file should not exceed 5,000. However, if the SR file is ingested into the Kepler Archivelet, then there is no restriction on the number of records contained in a SR file.

The government of the Republic of Indonesia had issued a regulation to substitute computer terms in foreign language that have been used earlier into official computer terms in Bahasa Indonesia. This regulation was stipulated in Presidential Decree No. 2 of 2001 concerning the introduction of official computer terms in Bahasa Indonesia (known as Senarai Padanan Istilah/SPI). After sixteen years, people of Indonesia, particularly for academics, should have implemented the official computer terms in their official publications. This observation is conducted to discover the implementation of official computer terms usage in scientific publications which are written in Bahasa Indonesia. The data source used in this observation are the publications by the academics, particularly in computer science field. The method used in the observation is divided into four stages. The first stage is metadata harvesting by using Open Archive Initiative - Protocol for Metadata Harvesting (OAI-PMH). Second, converting the harvested document (in pdf format) to plain text. The third stage is text-preprocessing as the preparation of string matching. Then the final stage is searching the official computer terms based on 629 SPI terms by using Boyer-Moore algorithm. We observed that there are 240,781 foreign computer terms in 1,156 scientific publications from six universities. This result shows that the foreign computer terms are still widely used by the academics.

Having indexed much of the "surface" Web, search engines are now using various approaches to index the "deep" Web. At the same time, institutional repositories and digital libraries are adopting the open archives initiative protocol for metadata harvesting (OAI-PMH) to expose their holdings. The authors harvested nearly 10 million records from OAI-PMH repositories. From these records, they extracted 3.3 million unique resource URLs and then conducted searches on samples from this collection to determine how much of the OAI-PMH corpus the three major search engines have indexed.

Cultural heritage is the way of life. Using digital technology to manage the information of cultural heritage has become an important issue on the perseverance of cultural heritage. Several cultural heritage institutions have their own large databases with different metadata schemas. Linked Open Data is a mechanism of publishing structured data that allows metadata to be connected. This paper presents a methodology for integrating, converting Lanna cultural heritage metadata and linking data to external data sources. Our framework uses OAI-PMH (Open Archives Initiative—Protocol for Metadata Harvesting) by converting the various metadata formats to Dublin Core metadata standard. The Dublin Core/XML was used for the integrated metadata to create a central repository of data sources. The OAI harvester was developed to extract data from the various repositories and gather data into the repository. A framework for publishing the repository data as a Linked Data source in the RDF format using the OAM Framework is described. In this framework, ontology is used as a common schema for publishing the RDF data from the database sources by mapping database schema to ontology. Finally, we demonstrate Linked Data consumption by creating a cultural heritage portal application prototype from the published RDF data sources.

This article presents a digital library solution for integrating data from a network of ecological sites using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) and the Open Digital Library (ODL) framework extended with geographic components. This solution incorporates simple, yet effective, decentralized input interfaces for handling heterogeneous data from unstructured sources. In this article, we focus on the architectural aspects of this solution and on an experimental evaluation, conducted with real users, of the proposed data input interface in terms of usability and data quality.

We present Opal, a light-weight framework for interactively locating missing web pages (http status code 404). Opal is an example of in vivo preservation: harnessing the collective behavior of web archives, commercial search engines, and research projects for the purpose of preservation. Opal servers learn from their experiences and are able to share their knowledge with other Opal servers by mutual harvesting using the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Using cached copies that can be found on the web, Opal creates lexical signatures which are then used to search for similar versions of the web page. We present the architecture of the Opal framework, discuss a reference implementation of the framework, and present a quantitative analysis of the framework that indicates that Opal could be effectively deployed.

In this paper we study the problem of representing, managing and exchanging hierarchically structured data in the context of a Digital Library (DL). We present the NEsted SeTs for Object hieRarchies (NESTOR) framework defining two set data models that we call: the Set Model (NS-M) and the Inverse Nested Set Model (INSM) based on the organization of nested sets which enable the representation of hierarchical data structures. We present the mapping between the tree data structure to NS-M and to INS-M. Furthermore, we shall show how these set data models can be used in conjunction with Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) adding new functionalities to the protocol without any change to its basic functioning. At the end we shall present how the couple OAI-PMH and the set data models can be used to represent and exchange archival metadata in a distributed environment.

Providing integrated access to islands of data warehouses has become one of the leading issues in data warehouse research and industry. This paper presents a framework for providing interoperability of distributed, heterogeneous, and autonomous data warehouses based on a federated approach. We focus on schema integration using XML, which offers significant benefits for interoperability, since it is a standardized, vendor and platform independent format for data and - in our case - metadata exchange.

It has been ten years since the publication of our first paper reporting on the beginning of a new national e- health interoperability journey in Australia and the interoperability framework developed by National e-health Transition Authority (NEHTA) [1]. Many new technologies, standard efforts and architecture approaches have emerged since then. Many new lessons were also learned by different stakeholders involved in using the framework as a basis for interoperability conversations and e-health solution development. Some of these were reflected in the second version of the NEHTA Interoperability Framework. This paper provides further details regarding this new version of the NEHTA Interoperability Framework, shows in more detail how Reference Model for Open Distributed Systems (RM-ODP) standards were used to provide underpinning foundations for interoperability, and lists some other development in e-health interoperability. Further, the paper describes the use of RM-ODP in other interoperability frameworks and describes links between interoperability frameworks, enterprise and solution architectures and interoperability methodologies.

During the last decades, document sharing has become vastly more available for the general public, with large document collections being made generally available on the internet and inside of organizations on intranets. In addition, each of us has an everincreasing archive of private digital documents. At the same time efforts to enable more efficient document retrieval have only succeeded marginally. This makes finding the right document like looking for a needle in the haystack. Just now it is a bigger haystack. This lack of overview of existing document resources results in large amounts of scarce human resources that are still being used to create similar resources.A key reason to why we are faced with this challenge is that few documents receive a sufficient metadata description in order to enable efficient retrieval. Too often the document metadata is insufficient or even incorrect. Few document creators are aware of describing their documents with metadata. Trained librarians and archivists can assist authors to create and publish metadata, but this is a costly and time-consuming process. Advanced metadata formats, such as the IEEE LOM, enable detailed and precise metadata descriptions. This format is challenging to use and the potential in the format is often not leveraged. Document formats that require such metadata, e.g. SCORM Learning Objects (LOs), are not being used to their potential due to the challenges of creating metadata.This thesis shows how Automatic Metadata Generation (AMG) can stand as a foundation for creation, publishing and discovery of document resources with rich and correct metadata descriptions. This thesis shows how high quality metadata can be created automatically using the documents themselves and contextual data sources. Finally, this thesis shows how metadata descriptions can be used alongside the original document to create SCORM LOs to enable sharing of educational resources with educational metadata descriptions.The main contributions by this thesis are:C1: Establishing an overview of research literature, projects and products using AMG and the quality of their generated metadata.C2: Establishing that AMG efforts can be combined to expand the range of elements and entities that can be generated, but also to increase the quality of generated entities.C3: Establishing that AMG efforts can generate high quality metadata from nonhomogeneous document collections, vastly expanding the practical usefulness of AMG.C4: Establishing that AMG efforts can contribute extensively in promoting sharing of knowledge with the creation of sharable SCORM LOs containing the educational resources themselves and extensive metadata descriptions to enable efficient location and use.
