3 Catalina Galán Saulnier y Evaristo Gestoso Rodriguez Lisboa 8 de Septiembre del 2006 Archaeological Spatial Data Infrastructures: Distributional and Collaborative Archaeology in Interoperability Framework INFRASTRUCTURES We can define an infrastructure of spatial data as an informatic system "Simple", powerfull and transparent that lets you access to the information that lies in it, using specifications, protocols and standards widely accepted. Data and services are de-centralized and lies in multiple nodes. Data are distributed in Server-Client Architecture: TCP/IP The ability of a system or components of the system to enter to a variety of hetereogeny resources by a simple interface.

4 Catalina Galán Saulnier y Evaristo Gestoso Rodriguez Lisboa 8 de Septiembre del 2006 Archaeological Spatial Data Infrastructures: Distributional and Collaborative Archaeology in Interoperability Framework INTEROPERABILITY  Distributed data through services interface ● Less redundant data ● Authoritative ● More effective data management ● Connect rather than hoard  Transparent / cooperative  Based on open specifications ● W3C, OGC  Normalizes playing field, independent ● Operating System ● Programming Languages ● Development Environments  ¿What's this? ● Web Services!

5 Catalina Galán Saulnier y Evaristo Gestoso Rodriguez Lisboa 8 de Septiembre del 2006 Archaeological Spatial Data Infrastructures: Distributional and Collaborative Archaeology in Interoperability Framework WEB SERVICES Web-based applications that dynamically interact with other Web applications using open standards that include XML/HTTP, UDDI, SOAP, WSDL, etc. Web services, unless they are independent, can have comunication between them and form groups of colaboration to make a specific task. The diference between a web page and a web service is that the first one is visited by any interested person, while the second is only visited by programs that requires it.
