Key Points l It’s about Data Integration and Data Sharing l Everyone is either one or more of these: 1. 2. 3. 4. A data source An Occasional default data sink (proactive) A hardwired data sink (proactive) A query sink (retroactive) We’ve begun: l l Relay Node – plasmus. ocean. washington. edu Wiring for example sink and source services Default source and sink services l Investigation of 39 program languages suited for XML-RPC services l l

Design Basis: a framework that simplifies all aspects of scientific data networking, allowing simple access to data Built upon the design principles of: • Division of Atmospheric Sciences (ATM) of the National Science Foundation (NSF) NSF UNIDATA program, and the Internet Data Distribution (IDD ) system, and • The NASA Earth Science Information Partners (ESIP) Federation DODS Distributed Oceanographic Data System

Design Principle l l Data are most appropriately described updated and distributed by those

Design Principle l l Data are most appropriately described updated and distributed by those that develop them; Users desire access ready for their existing application/software; It isn’t the scientists job to responding to data request; Users want access to data from anywhere that is served by the PRISM project regardless of its native format

Data SOURCE services Data RELAY services Data SINK services l l Multiple SOURCES: Data

Data SOURCE services Data RELAY services Data SINK services l l Multiple SOURCES: Data can be injected into the BLOODSTREAM from multiple sources where SOURCE SERVICES have been installed. Data recognition SINKS: Through a data recognition mechanism, users select from the available data only those needed for their needs. Reliable data delivery RELAYS: Reliable transport protocols ensure data accuracy at all sites. A queuing system buffers data flows at relays, preventing losses from network congestion and short outages. Load distribution: designed to avoid excessive concentration of network traffic. Generally, metadata flows with data. Only new data flow when needed.

What is XML-RPC? l A specification and a set of implementations that allow software

What is XML-RPC? l A specification and a set of implementations that allow software running on disparate operating systems, running in different environments to make procedure calls over the Internet. l Remote procedure calling services using HTTP as the transport and XML as the encoding. XML-RPC is designed to be as simple as possible, while allowing complex data structures to be transmitted, processed and returned.

Miles’ Parting Shots Remember: We’re trying to say: l l l Collaboration begins with sharing information Each of our projects is both a data source and data sink within the PRISM program By “communicating” through our data and information, we reduce the need for numerous solutions to similar tasks of data distribution, formatting, archiving, and retrieval tasks
