The latest publisher version (2.6.3) generates a THREDDS property 
'cmor_table':

...
    <property name="realm" value="atmos"/>
    <property name="cmor_table" value="3hr"/>
    <property name="ensemble" value="r1i1p1"/>
 ...

The esg.ini [project:cmip5] section needs a corresponding entry in the 
categories option:

categories =
...
  realm | enum | true | true | 5
  cmor_table | enum | true | true | 6
  ensemble | string | true | true | 7
...

and the enumerated values:

cmor_table_options = 3hr, 6hrLev, 6hrPlev, Amon, LImon, Lmon, OImon, 
Oclim, Omon, Oyr, aero, cf3hr, cfDay, cfMon, cfOff, cfSites, day, fx, grids

I'm not sure it matters as long as you're consistent. The 
'dataset_version' property should always be an integer, without the 'v' 
prepended.
