arcgisscripting and arcpy object model diagrams

[NathanWarmerdam]

For python scripters, the most useful piece of documentation at 9.x was the Geoprocessing Programming Model (seen here: http://webhelp.esri.com/arcgisdesktop/9.3/pdf/Geoprocessor_93.pdf).  This is extraordinarily useful because it presents the whole of arcgisscripting concisely on a single page.

In the documentation for 10.0, this item cannot be found for arcgisscripting or arcpy.  Can you please add this?

This is a no-brainer

An unofficial arcPy OMD has just been posted on the ArcGIS Forums.  Just for a nice poster to hang on your wall.

This is a must for any arcpy scripting geek.

I must agree with nbw.   I too found the Python GPM to be an essential part of my programming toolkit and would urge ESRI to continue providing this valuable tool in current ArcGIS versions

Was this ever implemented? The ArcObjects omds   were super helpful and I've never seen an arcpy equivalent.

@DrewDowling , after 10 years, we are here on this page again.
Not the answer but this might be of help (.NET)

To all concerned,

Thank you all for your feedback regarding the Object Model Diagram (OMD) for ArcPy. We've had another look at this idea, and the explanation provided by @ChrisFox remains accurate. The explanation is summarized below:

• Traditionally Python's own modules and other 3rd party site-packages do not carry OMDs.
• When the OMD was provided, conditions differed from now, which led to us producing the OMD, these conditions were:
  • The OMD was provided with arcgisscripting to help customers comfortable with ArcObjects and its OMD make the transition to Python.
  • With arcgisscripting, there was limited intellisence support and doc strings, so the OMD was provided to help navigate the package.
  • At ArcGIS 10, ArcPy was more than just a name change; it was a change in the way we organized and presented our Python implementation to be more in line with a true Python site-package.
• Since then, the help documentation for Python has been greatly improved:
  • The documentation structure follows the structure of ArcPy with a list of functions and classes and embedded links to related topics.
  • Fully fledged intellisense support and doc strings.
  • --update-- We now also have an ArcPy Cheatsheet: The ArcPy Cheatsheet - Esri Community

In addition, maintaining an OMD is very time consuming, so we have to weigh the benefit of reviving the OMD vs. other impactful work. After weighing these concerns, we concluded it will be more beneficial to spend this time on fixing bugs, developing features, and making sure the documentation continues to provide thorough and accurate information.

Thank you for your understanding,

- The Python team at esri

I've long thought that ArcGIS Desktop version 9.x was the last good version.  Something changed at 10.  As I stumbled onto this post 4 years after the final comment/answer, I realize that the decision by someone or someones-unknown at ESRI to not produce an OMD after 9.3 is likely to have been an indicator of that change.  Not a change for the better.
