Previous issue date: 2006-10-16 / A great challenge of the Component Based Development is the creation of mechanisms to facilitate the finding of reusable assets that fulfill the requirements of a particular system under development. In this sense, some component repositories have been proposed in order to answer such a need. However, repositories need to represent the asset characteristics that can be taken into account by the consumers when choosing the more adequate assets for their needs. In such a context, the literature presents some models proposed to describe the asset characteristics, such as identification, classification, non-functional requirements, usage and deployment information and component interfaces. Nevertheless, the set of characteristics represented by those models is insufficient to describe information used before, during and after the asset acquisition. This information refers to negotiation, certification, change history, adopted development process, events, exceptions and so on. In order to overcome this gap, this work proposes an XML-based model to represent several characteristics, of different asset types, that may be employed in the component-based development. Besides representing metadata used by consumers, useful for asset discovering, acquisition and usage, this model, called X-ARM, also focus on helping asset developers activities. Since the proposed model represents an expressive amount of information, this work also presents a tool called X-Packager, developed with the goal of helping asset description with X-ARM / O Desenvolvimento Baseado em Componentes tem como grande desafio a cria??o de mecanismos que facilitem a identifica??o de assets reus?veis que satisfa?am os requisitos de sistemas particulares sob desenvolvimento. Neste sentido, reposit?rios de componentes t?m sido propostos como meios para se atender esta necessidade. Por?m, reposit?rios precisam representar as caracter?sticas de assets que possam ser levadas em considera??o pelos consumidores quando da escolha dos assets mais adequados ?s suas necessidades. Neste contexto, a literatura apresenta alguns modelos que foram propostos com a finalidade de descrever as caracter?sticas de assets, tais como identifica??o, classifica??o, requisitos n?o funcionais, informa??es de implanta??o e uso, arquivos que comp?em os assets, e interfaces de componentes. No entanto, o conjunto de caracter?sticas representadas por estes modelos ? insuficiente para descrever diversas informa??es usadas antes, durante e depois da aquisi??o dos assets, dentre as quais pode-se destacar informa??es de negocia??o e certifica??o, hist?rico de mudan?as, processo de desenvolvimento usado, eventos, exce??es. De forma a solucionar tais defici?ncias, este trabalho apresenta um modelo baseado em XML para a representa??o de diversas caracter?sticas, de diversos tipos de assets, que possam ser empregadas no desenvolvimento baseado em componentes. O modelo proposto, denominado X-ARM, fornece informa??es usadas n?o apenas pelos consumidores na identifica??o, aquisi??o e uso de assets, mas tamb?m para apoiar as atividades dos desenvolvedores de assets. Dado que o modelo proposto representa uma expressiva quantidade de informa??es, este trabalho tamb?m apresenta uma ferramenta chamada X-Packager, desenvolvida com o objetivo de auxiliar a descri??o de assets com X-ARM
