© Keith G Jeffery, Anne G S Asserson GL New Orleans Background Previous papers on Grey literature by the authors (in the GL Conference Series) have described –the need for formal metadata to allow machine understanding and therefore scalable operations; –the enhancement of repositories of grey (and other) e-publications by linking with CRIS (Current Research Information Systems); –the use of the research process to collect metadata incrementally reducing the threshold barrier for end-users and improving quality in an ambient GRIDs environment. This paper takes the development one step further and proposes intelligent grey objects.
© Keith G Jeffery, Anne G S Asserson GL New Orleans Hypothesis The hypothesis is in 2 parts: –that the use of passive catalogs of metadata does not scale in a highly distributed environment with millions of nodes with vastly increased volumes of R&D output grey publications with associated metadata; –that a new paradigm is required that integrates grey with white literature and other R&D outputs such as software, data, products and patents in a self-managing, self-optimising way and that this paradigm manages automatically curation, provenance digital rights, trust, security and privacy.
© Keith G Jeffery, Anne G S Asserson GL New Orleans State of the Art Concerning the problem of scaling –Existing repositories catalogs - cost of input / update; –Harvesting takes increasing time - ensuring non-currency –To obtain and utilise results the end-user expends much manual effort / intelligence –The elapsed time of the network the centralised (or centrally controlled distributed) catalog server searches end-user intervention becomes unacceptable. Concerning the proposed solution –there is no paradigm currently known to the authors that satisfies the requirement - hence our proposal is developed.
© Keith G Jeffery, Anne G S Asserson GL New Orleans The Notion Hyperactive combines both –hyperlinking –active properties of a (grey) object. Hyperlinking implies multimedia components linked to form the object and also external links to other resources. The term active implies that objects do not (only) lie passively in a repository to be retrieved by end–users. They get a life and the object moves through the network knowing where it is going. Grey Object (eg hyperlinked Document) metadata Encapsulated object agent Active rules relationships
© Keith G Jeffery, Anne G S Asserson GL New Orleans How it Works A hyperactive grey object is wrapped by formal metadata, active rules, relationships, associated (software) agent. It moves through process steps The workflow is based on the rules and information in the CDR (Corporate Data Repository) and the active rules within the encapsulated grey object Once the object is deposited, the agent associated with it actively checks and builds the relationships On publication: the agent pushes the object to the end-users (or systems) The agents check the object and user (or system) restrictive metadata Alternatively the object can be found passively by end-user or system agents using its descriptive metadata. (again the agents check the restrictive metadata)
© Keith G Jeffery, Anne G S Asserson GL New Orleans Wider Context The object can also associate itself with other objects forming relationships utilising metadata or content. –Declared relationships include references and citations; –Workflowed relationships include versions and also links to corporate information and research datasets and software; –Inferenced relationships are discovered relationships such as between documents by different authors developed from an earlier idea of a third author.

© Keith G Jeffery, Anne G S Asserson GL New Orleans Current State Components of this paradigm have been implemented to some extent –Formalised metadata (and links to CRIS); –Active rules –Workflow using CDR; –Hyperlinking of Objects; –Inferencing (usually for plagiarism); –Agents –Self-* properties Much of it in a GRIDs environment
© Keith G Jeffery, Anne G S Asserson GL New Orleans Conclusion Keith G Jeffery Director, IT & International Strategy CCLRC Anne G S Asserson Research Department University of Bergen 1.Minimum effort by the end-user 2.Maximum input by system 3.Maximum use of information by system a)To manage workflow b)To manage relationships c)To generate relationships d)To assist retrieval 4.Scalable This surely is harnessing the power of grey.
