<H1>IVOA Theory: General requirements</H1>
<br/>
The general requirements form this page are meant
to guide the discussions and working of the Theory Interest Group.
The objective is to define a list of requirements needed to include theoretical models in general in the IVAO framework (i.e. related with other WG and IG). These requirements extends the ones taht can we extracted from  the [[IvoaTheoryUseCases][Use cases]] page.

---

<br/>
---++ General  requirements
   * Recover references of the theoretical models
   * Work with metadata different than RA & DEC 
   * Keep specifications for theoretical services as simple as possible in such a way that a "normal" researcher can include their results in the VO (it means, no much more difficult that to create a HTML page)

<br/>
---++ Applications requirements
How theoretical services can be access from applications? Would we push the App WG to include theoretical services at the same level of "cone-search-like" services? (linked with Registry requeriments).


<br/>
---++ Semantics requirements
See [[TheorySemanticVocabulary][Semantics]] for requirements

<br/>
---++ Data Acess Layer requirements
It is SNAP + TAP enough?, Should be TSAP (theoretical spectral access protocol) extended to other data services different than spectra?

<br/>
---++ Data Modeling requirements
Should each kind of theoretical result have a particluar data model? (data model for spectra + datamodel for isochrones + data model for photoionization + ....)?


<br/>
---++ Grids and Web services requirements
?

<br/>
---++ Regitry requirements
How to register theoretical models?
<br/>
<i>SNAP</i> Services approach: to register services that use SNAP and mantain a separated registry of SNAP resources(?) 
<br/>
<i>Non-SNAP</i> services: It refers to services that can use other protocools, like theoretical spectral as example that can use SSAP. Should these serviced registered as
SSAP or we must ask for an "special" entry inthe registry?
