| Abstract | This paper presents a two-layer model for the development of XML-based language compilers. In the first layer, a framework (generic compiler) is automatically generated from the XML Schema of a selected language (the input language). Besides defining the compiler structure, the generic compiler implements methods that can be reused by compilers of the selected input language. In the second layer, a compiler for a specific output data model is implemented, reusing the structure and methods specified by the framework. Based on this proposal, several compilers were built for some of the main hypermedia and multimedia authoring languages, including NCL, SMIL and XMT-O (MPEG-4).Este artigo apresenta um modelo em duas camadas para o desenvolvimento de processadores de linguagens baseadas em XML. Na primeira camada, um framework (processador genérico) é automaticamente gerado a partir do XML Schema de uma determinada linguagem (linguagem de entrada). Além de definir a estrutura de processamento, o processador genérico implementa métodos que podem ser reusados por implementações de processadores/compiladores para a linguagem de entrada selecionada. Na segunda camada, um processador para um modelo de dados de saída específico é implementado, reusando a estrutura e os métodos especificados pelo framework. Baseado nessa proposta, diversos conversores foram construídos para algumas das principais linguagens de autoria multimídia e hipermídia, incluindo NCL, SMIL e XMT-O (MPEG-4). |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
