Service Oriented Architecture (SOA)

Service Oriented Architecture Software architecture design pattern Method to organize distributed services Roles Efficient, scalable, easy to integrate Crucial role of standards Independent 8

9 Publish, Find, Bind patroon

Searching data 10

11 Searching spatial data What are the “find” technologies Catalog service (Geoportal or Clearinghouse) Metadata

Catalog service 12 Standard for publishing catalog of spatial data on the web Publishing by means of metadata Functions: Discovery, Query, Browse More information: alog

Searching spatial data 13 Metadata

Searching spatial data 14 Catalog services

15 link

Exercise 16 Take a 20 minutes and search several datasets from SDI Geoportals Analyze their metadata: Who is the data provider? Are there any use restrictions? How dataset quality is described? How can the dataset be accessed? Be able to shortly discuss your findings.

Publishing spatial data 17

Publishing spatial data 18 Metadata (editor) Metadata publish to catalog service Keeping data and services at one source location

Publish technology 19
