Discovery Hack-a-thon Details
Overview
What's the Plan? Get together to make some simple Discovery clients! All are welcome, no previous experience or coding skills necessary!
- Two back-to-back sessions:
Abstract: The set of ESIP Discovery services encompass the overlapping conventions of Earth science federated OpenSearch, Collection Casting, Granule Casting, and Service Casting feed standards. To help lower the barrier of entry, we will provide a set of hands-on and simple approaches to using Discovery services. These include walking through some "low-hanging fruit" approaches to calling OpenSearch, Collection Casting, Granule Casting, and Service Casting.

Discovery Hack-a-thon Overview (20-mins)
Quick overview of ESIP Discovery services and set the stage for call the ESIP Discovery services from various simple clients.
Poll the audience for interest.
Hack-a-thon Breakout (70-mins)
Geoportal
We will have a Geoportal from our testbed up and running. You'll learn what protocols the geoportal already supports for service validation, how to use the geoportal to validate and register data and services, and how to add configurations for validation to a geoportal instance. Or, just take the Discovery Cluster geoportal instance out for a spin!
Mentor: Christine White
Browsers and News Readers
It's even possible to interact with both Data "casts" and OpenSearch servers using a simple browser. Also, News Readers, especially useful for Data casts!
Mentors: Ruth Duerr and ...
Cast Publishing and Aggregation
Learn how to use existing web apps create 1-off data casts. Come, create a cast or two and then see it found (that's the idea anyway).
Mentors: Ruth Duerr and ...
Command line
Yes, you can interact with an OpenSearch server or a Data Cast using basic command-line URL getters, like wget (available for all platforms) and curl.

Perl Monks
Learn how to hack a quick client together. Particularly useful for doing scripted search/acquire for datasets following your own, possibly idiosyncratic needs.
Mentors: Chris Lynnes and ...
Python Scripters
Learn how to use Python, an easy to use, but powerful scripting language, to interact with OpenSearch servers and find the data you need.
Mentors: Nga Chung and ...
Java Programmers
Mentors: Eric Rozell and ...
XSL Transforms
Learn how to generate simple interfaces to OpenSearch cast feeds. ESIP Discovery casts extend the Atom casts format and thus these transforms will expose additional information to the user interface.
