Design of metadata elements for digital news articles in the omnipaper project

This paper examines and proposes a set of metadata elements for describing digital news articles for the benefit of distributed and heterogeneous news resource discovery. Existing digital news description standards such as NITF and NewsML are analysed and compared with Dublin Core Metadata Element Set (DCMES), which results in that the use of Dublin Core is encouraged for interoperability of the resources. The suggested metadata elements are carefully selected and defined considering the characteristics of news articles. Some elements are detailed with refinement qualifiers and recommended encoding scheme. This set of metadata has been developed as a part of the tasks in the IST (Information Society Technologies)-funded European project OmniPaper (Smart Access to European Newspapers, IST-2001-32174)

Omnipaper – Arquitectura de metadados e sua implementação no RDF gateway

O projecto Omnipaper (Smart Access to European Newspapers) é um projecto do programa IST (Information Society Technologies) da comissão europeia, que visa fomentar um acesso comum a diferentes tipos de fontes de informação distribuída. Pretende-se chegar a um protótipo de um sistema que permita aos utilizadores (quer ocasionais, quer profissionais) um acesso estruturado, personalizado e multilíngua a todo o manancial de artigos de notícias disponibilizados pelas empresas parceiras (a que chamamos arquivos locais). Um dos aspectos fundamentais do projecto é toda a camada de metadados do sistema. Na verdade, falamos de duas camadas de metadados: (1) uma primeira camada (Local Knowledge Layer) que é adicionada aos arquivos locais e tem como principal objectivo proporcionar uma descrição semântica de todos os artigos existentes; e (2) uma segunda camada (Overall Knowledge Layer), a um nível de abstracção mais elevado que recorre á primeira para proporcionar um ambiente integrado e estruturado de navegação, e pesquisa possibilitando, quando possível uma ligação a um ambiente multilingua. Neste artigo focalizamos a nossa atenção no Local Knowledge Layer e apresentamos as estruturas de metadados utilizadas, bem como as descrições tipo RDF/XML dos diferentes géneros de artigos de notícias incluídos no protótipo. A sua implementação foi realizada, utilizando um ambiente RDF ainda em de fase de testes – o RDF Gateway. Neste momento, esta ferramenta é o suporte ao desenvolvimento do protótipo, na manipulação e tratamento de informação estruturada em RDF. Os primeiros resultados e as análises decorrentes do desenvolvimento deste protótipo, são apresentados como conclusão deste artigo

Implementation of metadata for OmniPaper RDF prototype

Information Society Technologies (IST) funded OmniPaper project investigates efficient ways for access to distributed and heterogeneous digital news archives using state-of-the-art technologies such as RDF, XTM and SOAP. An approach taken is to create small prototypes based on each of them. This paper presents the first stage of the prototype development, particularly of RDF approach, including analysis on existing news text format standards and metadata vocabularies, definition of metadata elements for OmniPaper, implementation of application profile and RDF schema and development of the RDF prototype in a web-based RDF specific application. The elaborated analysis shows that Dublin Core Metadata Element Set has to be a principal vocabulary to implement the OmniPaper application profile as it provides greater interoperability. The RDF prototype provides RDF “metadatabase” with searchable interface for simple and advance search on the defined metadata elements

Measurement and analysis of the elastic-plastic deformation behavior of an ultra-thin austenitic stainless steel sheet subjected to in-plane reverse loading.

In order to clarify the deformation behavior of an ultra-thin austenitic stainless steel sheet (SUS301) used for manufacturing electronic parts a new testing devise is designed and built. The test material is 0.2 mm thick and has a 0.2 % proof stress of 1800 MPa. The testing apparatus is equipped with comb-type die couples to measure the stress-strain curves of the sample under tension-compression cyclic loading without buckling for a strain amplitude of 0.017. It is found that the stresses are higher in tension than in compression in the rolling direction (RD) for a strain range of lel 0.002, while in the transverse direction (TD) the stresses are higher in compression than in tension, and that the test material showed significant difference in the cyclic loading behavior between the RD and TD.
