This paper discusses ongoing research on scientific workflows at the Institute of Computing, University of Campinas (IC - UNICAMP) Brazil. Our projects with bio-scientists have led us to develop a scientific workflow infrastructure named WOODSS. This framework has two main objectives in mind: to help scientists to specify and annotate their models and(More)
The Web is evolving from a space for publication/consumption of documents to an environment for collaborative work, where digital content can travel and be replicated, adapted, decomposed, fusioned, and transformed. We call this the fluid Web perspective. This view requires a thorough revision of the typical document-oriented approach that permeates content(More)
The Semantic Web has opened new horizons in exploring Web func-tionality. One of the many challenges is to proactively support the reuse of digital artifacts stored in repositories all over the world. Our goal is to contribute towards this issue, proposing a mechanism for describing and discovering ar-tifacts called Digital Content Components (DCCs). DCCs(More)
Many web-based public repositories are widely adopting tag-based metadata approaches as their main classification mechanism. This phenomenon is fostering initiatives to improve the semantic interpretation of tags, usually involving two main entities: "social ontologies", which emerges from the collaborative tagging (folksonomies), and formal ontologies. In(More)
Scientific models are increasingly dependent on processing large volumes of streamed sensing data from a wide range of sensors, from ground based to satellite embarked infrareds. The proliferation, variety and ubiquity of those devices have added new dimensions to the problem of data handling in computational models. This raises several issues, one of which(More)
