The METAFOR project: preserving data through metadata standards for climate models and simulations

Climate modeling is a complex process, requiring accurate and complete metadata in order to identify, assess and use climate data stored in digital repositories. The preservation of such data is increasingly important given the development of ever-increasingly complex models to predict the effects of global climate change. The EU METAFOR project has developed a Common Information Model (CIM) to describe climate data and the models and modelling environments that produce this data. There is a wide degree of variability between different climate models and modelling groups. To accommodate this, the CIM has been designed to be highly generic and flexible, with extensibility built in. METAFOR describes the climate modelling process simply as "an activity undertaken using software on computers to produce data." This process has been described as separate UML packages (and, ultimately, XML schemas). This fairly generic structure canbe paired with more specific "controlled vocabularies" in order to restrict the range of valid CIM instances. The CIM will aid digital preservation of climate models as it will provide an accepted standard structure for the model metadata. Tools to write and manage CIM instances, and to allow convenient and powerful searches of CIM databases,. Are also under development. Community buy-in of the CIM has been achieved through a continual process of consultation with the climate modelling community, and through the METAFOR team’s development of a questionnaire that will be used to collect the metadata for the Intergovernmental Panel on Climate Change’s (IPCC) Coupled Model Intercomparison Project Phase 5 (CMIP5) model runs.

Metadata Authority Description Schema (MADS): uma alternativa à utilização do formato MARC 21 para dados de autoridade

Introduction: Authority records interchange requires establishing and using metadata standards, such as MARC 21 Format for Authority Data, format used by several cataloging agencies, and Metadata Authority Description Schema (MADS), that has received little attention and it is a little widespread standard among agencies. Purpose: Presenting an introductory study about Metadata Authority Description Schema (MADS). Methodology: Descriptive and exploratory bibliographic research. Results: The paper address the MADS creation context, its goals and its structure and key issues related to conversion of records from MARC 21 to MADS. Conclusions: The study concludes that, despite its limitations, MADS might be used to create simple authority records in Web environment and beyond libraries context.

Survey and Mapping Infrastructure Regulation 2004- Comments Relating to a 10-Year Review

Democratic governments raise taxes and charges and spend revenue on delivering peace, order and good government. The delivery process begins with a legislature as that can provide a framework of legally enforceable rules enacted according to the government’s constitution. These rules confer rights and obligations that allow particular people to carry on particular functions at particular places and times. Metadata standards as applied to public records contain information about the functioning of government as distinct from the non-government sector of society. Metadata standards apply to database construction. Data entry, storage, maintenance, interrogation and retrieval depend on a controlled vocabulary needed to enable accurate retrieval of suitably catalogued records in a global information environment. Queensland’s socioeconomic progress now depends in part on technical efficiency in database construction to address queries about who does what, where and when; under what legally enforceable authority; and how the evidence of those facts is recorded. The Survey and Mapping Infrastructure Act 2003 (Qld) addresses technical aspects of where questions – typically the officially recognised name of a place and a description of its boundaries. The current 10-year review of the Survey and Mapping Regulation 2004 provides a valuable opportunity to consider whether the Regulation makes sense in the context of a number of later laws concerned with management of Public Sector Information (PSI) as well as policies for ICT hardware and software procurement. Removing ambiguities about how official place names are to be regarded on a whole-of-government basis can achieve some short term goals. Longer-term goals depend on a more holistic approach to information management – and current aspirations for more open government and community engagement are unlikely to occur without such a longer-term vision.

A identificação de metadados de assunto para a legislação federal brasileira : o caso do Sistema Legin Web da Câmara dos Deputados

Aponta aspectos que devem ser considerados na identificação de metadados de assunto granulares para a legislação federal brasileira. O objeto de estudo foi o Sistema de Legislação Informatizada (Legin Web) disponível no Portal da Câmara dos Deputados. Os objetivos específicos foram: identificar tipos de assuntos amplamente utilizados na indexação da legislação federal brasileira e aspectos do contexto de busca de informação que interferissem na identificação dos metadados de assunto; analisar possibilidades de metadados de assunto para a legislação federal com base em padrões de metadados e modelos de organização da informação abordados na literatura; e, com isso, propor metadados de assunto para a legislação federal brasileira. A ideia é usar esses metadados para diminuir a imprecisão dos resultados das pesquisas na legislação federal, tornando o processo mais rápido e eficiente.

Ontology based Framework for News Extraction in Visual Media

Anticipating the increase in video information in future, archiving of news is an important activity in the visual media industry. When the volume of archives increases, it will be difficult for journalists to find the appropriate content using current search tools. This paper provides the details of the study we conducted about the news extraction systems used in different news channels in Kerala. Semantic web technologies can be used effectively since news archiving share many of the characteristics and problems of WWW. Since visual news archives of different media resources follow different metadata standards, interoperability between the resources is also an issue. World Wide Web Consortium has proposed a draft for an ontology framework for media resource which addresses the intercompatiblity issues. In this paper, the w3c proposed framework and its drawbacks is also discussed
