= Welcome to the SDO Heliophysics Event Knowledgebase Wiki =
This wiki supports development and use of the [[http://www.lmsal.com/helio-informatics/hpkb/|HEK]] software system for use by  [[http:hmi.stanford.edu|HMI]] and [[http://aia.lmsal.com|AIA]] instruments on the Solar Dynamics Observatory (SDO) mission. Intended readers are regular users of SDO data or HEK softwar and developers of HEK software.

This is a work in progress. So Be warned!

== Overview ==
Data collected by the AIA instrument be used to generate a variety of data products. A schematic of these and the steps in generating them is displayed here: [[attachment:AIA_highleveldataproductsp2.pdf]]. These products are the result of analysis and automated processing in the Lockheed Martin Solar and Astrophysics Laboratory's Level 2 system, [[attachment:SDOEventSystem.tiff]]. A draft for the types of events, data expected to be required to find them, possible detection methods, etc are show here: [[attachment:AIA_highleveldataproductsp3.pdf]]. Similarly, higher level products we expect to generate are summarized here: [[attachment:AIA_highleveldataproductsp4.pdf]]. More information is available here: [[attachment:AIAEventOverview.pdf]].


== Components ==
=== Registries ===
This is for materials on the Heliophysics Event Registry (HER, aka [[http://www.lmsal.com/helio-informatics/hpkb/|HPKB]]), Heliophysics Coverage Registry (HCR, see [[http://sot.lmsal.com/sot-data|LMSAL Hinode Data Center]] for prototype) and the [[http://www.lmsal.com/hpkb/pod|Movie Registry]].

== Protocols & Standards ==
For the components of HEK to work, we have adopted certain protocols and standards. These will be documented here. Currently these are the Event Schema, Solarsoft and REST-style webservices.

=== Event Schema ===
HEK has adopted an enhanced form of the [[http://ivoa.net/internal/IVOA/IvoaVOEvent/VOEvent_v1.1.html|VOEvent]] standard. In addition to some minor changes to better support heliophysical events, the HEK is developing a schema for classifying and describing features and events.
