The Need for a Meta-Tag Standard for Audio and Visual Materials
Get PDFIn Canada, as elsewhere around the world, government is trying to move into the Internet Age, to communicate
more and more interactively with an everincreasing portion of the electorate and to increase the interoperability of digitized media. The Canadian Government Online Initiative, of which we are a part, is an example of this trend. To facilitate access to our materials, we need metatags, metatags that, by and large were originally set up to deal with print media. Thus, we have been struggling in recent years to apply metadata to a test database of Canadian cultural audio and visual clips that we call "Heritage Line". We have followed many avenues for making our data searchable and accessible. We have used the Dublin Core schema, both with the qualified set of elements as well as the unqualified set. Our problems arose specifically with respect to the elements 'type'
and 'format'. Mpeg-7 currently appears to offer a solution to our problem
Development and Application of Dublin Core Metadata Standards in Marathi
No full textTo enable Dublin Core metadata to become a global standard for locating information on the Web, it is essential that such metadata be provided in different languages and in a variety of scripts. This would enable search and retrieval of Web documents in all languages. Considering the potentials of DC metadata in resource discovery on the Internet, the current paper reports an attempt to translate Dublin Core metadata elements into Marathi language (the local language of Maharashtra State in India), render them in Devnagari script and apply them to a significant section of Marathi literature – viz. the writings of one of the "saint-poets" of the Middle Ages.
Our efforts are to create a web based database and to assign Dublin Core international metadata standards rendered in Marathi for cataloguing the literature of one of the prominent “saint-poets” – Chokha Mela – available in print and electronic format as well as on Internet. This is conceived as part of a larger project of organizing all the literature of the "saint-poets".
We have chosen a group of saint-poets" in Maharashtra from the 13th century (e.g. Jnandev 1275-96) to the 17th century (e.g. Tukaram 1608-90) whohelped establish the 'Bhakti' (devotional) school of Hinduism in Western India and assisted in its spread from southern to northern India. Even today, the lives of the saint-poets and their literature continue to inspire a large section of the Marathi speaking population and provide them with emotional solace. As such, their writings constitute an important segment of Marathi literature and researchers from all over the world are engaged in studying it. The original writings in Sanskrit (including the early handwritten manuscripts) and commentaries in Marathi on them are scattered at different places in India and are now beginning to make an appearance on the Web
A Comprehensive Framework for Building Multilingual Domain Ontologies: Creating a Prototype Biosecurity Ontology
No full textThis paper presents our ongoing work in establishing a multilingual domain ontology for a biosecurity portal. As a prototypical approach, this project is embedded into the bigger context of the Agricultural Ontology Service (AOS) project of the Food and Agriculture Organization (FAO) of the UN. The AOS will act as a reference tool for ontology creation assistance and herewith enable the transfer of the agricultural domain towards the Semantic Web. The paper focuses on introducing a comprehensive, reusable framework for the process of semi-automatically supported ontology evolvement, which aims to be used in follow-up projects and can eventually be applied to any other domain. Within the multinational context of the FAO, multilingual aspects play a crucial role and therefore an extendable layered ontology modelling approach will be described within the framework. The paper will present the project milestones achieved so far: the creation of a core ontology, the semiautomatic extension of this ontology using a heuristic toolset, and the representation of the resulting ontology in a multilingual web portal. The reader will be provided with a practical example for the creation of a specific domain ontology, which can be applied to any possible domain. Future projects, including automatic text classification, and ontology facilitated search opportunities, will be addressed at the end of the paper
Abstraction versus Implementation: Issues in Formalizing the NIEHS Application Profile
No full textThis poster documents issues in formalizing the National Institute of Environment Health Sciences (NIEHS) Application Profile, specifically the changes implemented between Version 1 to Version 2, which were influenced by revisions made
to the NIEHS metadata form supporting author-generated metadata
Exposing Cross-Domain Resources for Researchers and Learners
No full textMIMAS is a national UK data centre which provides networked access to resources to support learning and research across a wide range of disciplines. There was no consistent way of discovering information within this cross-domain, heterogeneous collection of resources, some of which are access restricted. Further these resources must provide the interoperable interfaces required within the UK higher and further education 'information environment'. To address both of these problems, consistent, high quality metadata records for the MIMAS services and collections have been created, based on Dublin Core, XML and standard classification schemes. The XML metadata repository, or 'metadatabase', provides World Wide Web, Z39.50 and Open Archives Initiative interfaces. In addition, a collection level database has been created with records based on the RSLP Collection Level Description schema. The MIMAS Metadatabase, which is freely available, provides a single point of access into the disparate, cross-domain MIMAS datasets and services
Archon – A Digital Library that Federates Physics Collections
No full textArchon is a federation of physics collections with varying degrees of metadata richness. Archon uses the Open Archives Initiative Protocol for Metadata Harvesting (OAIPMH) to harvest metadata from distributed archives. The architecture of Archon is largely based on another OAIPMH digital library: Arc, a cross archive search service. However, Archon provides some new services that are specifically tailored for the physics community. Of these services we will discuss approaches we used to search and browse equations and formulae and a citation linking service for arXiv and American Physical Society (APS) archives
Visualising Interoperability: ARH, Aggregation, Rationalisation and Harmonisation
No full textThis paper proposes a visualisation of interoperability to assist real-world deployment of metadata. For some time, resource managers in many organisations have been acting on faith, creating 'standards compliant' metadata with the aim of exposing their resources to provide interoperability in discovery activities. In some cases, their faith has led them to miss the very essence of the work they are doing, and they have not got what they worked for. The authors report a case study involving government agencies in Victoria, Australia. A number of departmental agencies have implemented, more or less, the DC-based Australian Government Locator Service (AGLS) application profile, at least for their web resources. They have done this with care and precision, with the long-term aim of developing a fully interoperable system. In the case study, typical would-be records for seven government departments were studied and it was shown that the tiniest, and typical, variation in use of the standard can be expected to thwart the aimsof interoperability in significant ways.
In the context of the government’s move to seeking interoperable metadata for all resources, including those within document management systems, the authors make visible how a small 'creep' can lead away from interoperability and how it might be contained in the future. They use a 3-step approach of 'aggregation, rationalisation and harmonisation' to expose the problems with 'nearly good enough' interoperability and the benefits of good interoperability, and encourage true harmonisation
Semantic Web Construction: An Inquiry of Authors’ Views on Collaborative Metadata Generation
No full textIncreasing the amount and quality of metadata is essential for realizing the Semantic Web. The research reported on in this article addresses this topic by investigating how resource authors might best collaborate with metadata experts to expedite and improve metadata production. Resource authors, working as scientists at the National Institute of Environmental Health Sciences (NIEHS), were surveyed about collaborating with metadata experts (catalogers) during the metadata creation process. The majority of authors surveyed recognized cataloger expertise is important for organizing and indexing web resources and support the development of a collaborative metadata production operation. Authors discovered that, as creators of web resource intellectual content, they too have knowledge valuable for cataloging. This paper presents the study’s framework and results, and discusses the value of collaborative metadata generation for realizing the Semantic Web
District Architecture for Networked Editions: Technical Model and Metadata
No full textDistrict Architecture for Networked Editions (DAFNE) is a research project funded by the Italian Ministry of Education, University and Research aiming to develop a prototype of the national infrastructure for electronic publishing in Italy. The project’s initial target concerns the scientific and scholarly production in the human and social sciences. The organizational, legal, technical and business aspects of the entire digital publishing pipeline have been analysed. DAFNE system will support the request-offer chain by promoting the integration between the digital library and the electronic publishing districts. In this paper we present the main results of the project’s first year of activity. First a quick outlook about the actors, objects and services is presented. Then the functional model is examined bringing out the distinction between information content and digital objects. Afterwards the technical model is described. The system has a distributed architecture, which includes three categories of subsystems: Data Providers (i.e. the publishers), Service Providers and External Services. Data and Service Providers interact according to the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). Finally DAFNE metadata is discussed. Metadata permeates the whole publishing chain and DAFNE metadata set is based on already defined domain-specific metadata vocabularies. Dublin Core Metadata Initiative (DCMI) and Publishing Requirements for Industry Standard Metadata (PRISM) are the main reference standards. Open Digital Rights Language (ODRL) and Open Archival Information System (OAIS) are the two other relevant models which complete DAFNE metadata specification
