Earth observing system. Data and information system. Volume 2A: Report of the EOS Data Panel

The purpose of this report is to provide NASA with a rationale and recommendations for planning, implementing, and operating an Earth Observing System data and information system that can evolve to meet the Earth Observing System's needs in the 1990s. The Earth Observing System (Eos), defined by the Eos Science and Mission Requirements Working Group, consists of a suite of instruments in low Earth orbit acquiring measurements of the Earth's atmosphere, surface, and interior; an information system to support scientific research; and a vigorous program of scientific research, stressing study of global-scale processes that shape and influence the Earth as a system. The Eos data and information system is conceived as a complete research information system that would transcend the traditional mission data system, and include additional capabilties such as maintaining long-term, time-series data bases and providing access by Eos researchers to relevant non-Eos data. The Working Group recommends that the Eos data and information system be initiated now, with existing data, and that the system evolve into one that can meet the intensive research and data needs that will exist when Eos spacecraft are returning data in the 1990s

Hypermedia-based discovery for source selection using low-cost linked data interfaces

Evaluating federated Linked Data queries requires consulting multiple sources on the Web. Before a client can execute queries, it must discover data sources, and determine which ones are relevant. Federated query execution research focuses on the actual execution, while data source discovery is often marginally discussed-even though it has a strong impact on selecting sources that contribute to the query results. Therefore, the authors introduce a discovery approach for Linked Data interfaces based on hypermedia links and controls, and apply it to federated query execution with Triple Pattern Fragments. In addition, the authors identify quantitative metrics to evaluate this discovery approach. This article describes generic evaluation measures and results for their concrete approach. With low-cost data summaries as seed, interfaces to eight large real-world datasets can discover each other within 7 minutes. Hypermedia-based client-side querying shows a promising gain of up to 50% in execution time, but demands algorithms that visit a higher number of interfaces to improve result completeness

The New Technology and Competencies for "The Most Typical of the Activities of Libraries": Technical Services

At a library conference in 1940, William M. Randall called technical services the "most typical of the activities of libraries" "they are..." he said, "the things which librarians do that no one else does the secrets of the craft." 1 In those intervening forty-three years much has been written and uttered in defense and derision of these "secrets of the craft." These most typical of library activities have changed the name Randall used, technical processes, to technical services. They have moved from being sneeringly derided as "backroom," "basement" or other dreary location activities to being enthusiastically hailed today as "where the action is." They are, fortunately, no longer the "secrets" that they were in Randall's day. They have been moved into, moved around within and even moved out of the organizational charts. Regardless of all these attitudes and activities, the functions of acquiring, organizing and preserving library materials persist and the competencies necessary to carry out these three functions will be the focus of this paper. In the paper, reference will frequently be made to the "technical services librarian" meaning any librarian who works in that aspect of librarianship. The emphasis is on no particular type of library. The term library will be used as meaning also information center.published or submitted for publicatio
