A data portal is a web site that
functions as a point of access to
information, data, and models from
diverse sources in a unified way.

1. There is a Java program (“the SERAP server”) running on
a web accessible machine (see the URL).
2. The server requires programming.
3. Access to the port that this server listens to is configurable
(i.e. public access, USGS only, selected IPs only, etc.)
4. The server and the machine that run the server require
maintenance and upkeep.
How the SERAP Data Portal WorksSERAP Server

1. Have a web server running on an accessible machine.
Your system administrators can do this for you.
2. Write an XML configuration file. This sets up the data
request forms on the web page.
3. Put data files in a directory structure according to the XML
configuration file
4. Keep the web server running

1. Everybody needs to agree on boxes and arrows in diagram
2. Each box is assigned to someone
3. Everyone has to agree on spatial resolution, common nodes,
time periods, time steps
4. Everyone has to agree on simulation scenarios, evaluation
criteria
5. Someone (with resources) has to set up and maintain the
server
