---+ Photometry Data Model 1.1 Proposed Recommendation: Request for Comments
---++ Introduction

PHOTDM v1.1 is a revision of 'PhotDM v1.0', redesigned to follow the rules and constraints set by the VODML meta-model definition. The goals are warrant backward compatibility as much as possible. Keep the same concepts as in version <span style="background-color: transparent;"> </span><span style="background-color: transparent;">PhotDMv1</span><span style="background-color: transparent;">-1 v1.0 provide the </span><span style="background-color: transparent;">PhotDMv1</span><span style="background-color: transparent;">-1.vo-dml.xml description of all classes in VODML format all relations between classes and attributed are kept as much as possible. for backward compatibility, Utypes previously defined the previous REC Phot DM 1.0 document and listed in appendix B should not be changed after this update. The benefit is to keep interoperability with the SVO Filterprofile service which has grown to a full Filter repository and represents a kind of Filter registry for the Multi-wavelength community. The new VODML representation allows building photometric annotations for various kinds of data products: catalogs, spectra, lightcurves, cubes, etc.</span>

The latest version of the model and supporting docs:
   * RCF Document versions (IVOA repository) 
      * [[https://www.ivoa.net/documents/PHOTDM/20220301/index.html][PDF]]
   * <span style="background-color: transparent;">Development Version: (Git Repository) </span>

---++ Implementation Requirements
   * [[https://github.com/ivoa-std/MANGO][<strong>MANGO</strong>]] is a proposal for a model designed to enhance the interoperability of catalogue data. The MANGO model is based on native classes the aggregate imported objects among those PhotDM classes are.
   * <strong>VO Model Annotation Syntax </strong>([[https://github.com/ivoa-std/ModelInstanceInVot][VOMAS]]) is a draft for an XML schema allowing to map VOTable data on any model. This draft comes with another repository ([[https://github.com/ivoa/modelinstanceinvot-code][modelinstanceinvot-code]]) that gathers codes that are being developped to exercise the mapping syntax on real data. 2 of these tools are working with PhotDM model: 
      * This project contain a few Jupyter notebooks that can be launched [[https://mybinder.org/v2/gh/ivoa/modelinstanceinvot-code/merge-syntax][online]]
      * *SED Builder*: A [[https://github.com/ivoa/modelinstanceinvot-code/blob/merge-syntax/python/examples/example.6.NWAYAWGXMM.py][VOTable]] that gathers photometric data from XMM, 2MASS, WISE and Gaia has been annotated with PhotDM. A demo ([[https://github.com/ivoa/modelinstanceinvot-code/blob/merge-syntax/python/examples/example.6.NWAYAWGXMM.py][standalone]] or [[https://github.com/ivoa/modelinstanceinvot-code/blob/merge-syntax/photdm_impl.ipynb][notebook]] ) reads this VOTABLE and plots one SED fot each data row after having converted MAGs into fluxes when requested.
      * <strong>Serialization of FPS output: </strong>A [[https://github.com/ivoa/modelinstanceinvot-code/tree/merge-syntax/python/scripts][script]] generates XML snippets from FPS output applied to a template. These snippets contain XML serializations of both _PhotDM:PhotmetrySystem_ and <em>PhotDM:</em><em>PhotCal</em> that can be used as components for further VOTable annotations.
