What terms does your metadata use? Application profiles as machine-understandable narratives

2001 , Baker, T. , Dekkers, M. , Heery, R. , Patel, M. , Salokhe, G.

The SCHEMAS Registry aims at providing a selected and annotated overview of metadata vocabularies and their use in application environments. Based on harvested metadata in RDF (Resource Description Framework), the registry allows users to explore links between "namespace schemas", which declare standard definitions of metadata terms, and "application profiles" ? RDF statements about the use or adaptation of namespace terms for particular domains, services, or projects. Where instance metadata does not follow standard namespaces or explicit data models, this style allows implementors to assert an explicit mapping to standard terms. Registering profiles can help harmonize metadata usage in particular domains and, in the longer term, could provide a machine-processable basis for automating crosswalks and conversions.

Numerical methods for the three-dimensional two-body problem in the action-at-a-distance electrodynamics

2001 , Nikitin, I.N. , Luca, J. de

We develop two numerical methods to solve the differential equations with deviating arguments for the motion of two charges in the action-at-a-distance electrodynamics. Our first method uses Sturmer's extrapolation formula and assumes that a step of integration can be taken as a step of light ladder, which limits its use to shallow energies. The second method is an improvement of pre-existing iterative schemes, designed for stronger convergence and can be used at high-energies.
