Con la ayuda de Mark Cederholm, tengo una solución de trabajo que utiliza python y arcobjects . Es duro por los bordes, pero hizo el trabajo. Después de seguir la receta en esa página, cree un nuevo script que use las GetLibPath, NewObj, CType, OpenFeatureClassfunciones de snippets.py. También cree las tablas de búsqueda de cambio de nombre en formato .csv:
Búsqueda de alias de campo a campo (att_code-name_lookup.csv):
Attrib_Name,Alias_Name
CODE,Specification Code
VALDATE,Validity Date
...
Clase de entidad para la búsqueda de FC Alias (fc_code-name_lookup.csv):
"FC_Name","AliasName"
"BS_1250009_0","Navigational Aid"
"BS_1370009_2","Residential Area"
...
y el guión:
import sys
sys.path.append('k:/code')
from snippets import GetLibPath, NewObj, CType, OpenFeatureClass
sWorkingDir = "k:/code/"
sFileGDB = sWorkingDir + "blank_canvec.gdb"
sResourceDir = "k:/code/"
sFCAliasFile = sResourceDir + "fc_code-name_lookup.csv"
sAttAliasFile = sResourceDir + "att_code-name_lookup.csv"
sProduct = "ArcEditor"
def BuildFieldAliasLookup():
lookup = {}
f = open(sAttAliasFile, "r")
bFirst = True
for line in f:
# Skip first line
if bFirst:
bFirst = False
continue
sTokens = line.replace('"','').split(',')
sFieldName = sTokens[0]
sAlias = sTokens[1]
lookup[sFieldName] = sAlias
return lookup
def AlterAlias():

import comtypes.gen.esriGeoDatabase as esriGeoDatabase
gp = arcgisscripting.create(9.3)
try:
gp.setproduct(sProduct)
except:
gp.AddMessage(gp.GetMessages(2))
# Build field alias lookup table
AttrLookup = BuildFieldAliasLookup()
# Open alias file and loop through lines
f = open(sFCAliasFile, "r")
bFirst = True
for line in f:
# Skip first line
if bFirst:
bFirst = False
continue
sTokens = line.replace('"','').split(',')
sFCName = sTokens[0]
sAlias = sTokens[1]
print "Processing: ", sFCName
# Open feature class
try:
pFC = OpenFeatureClass(sFCName)
except:
print "Could not open ", sFCName
continue
# Alter feature class alias
try:
pSE = CType(pFC, esriGeoDatabase.IClassSchemaEdit)
pSE.AlterAliasName(sAlias)
except:
print "Error altering class alias"
continue
# Alter field aliases
try:
for sKey in AttrLookup.keys():
i = pFC.FindField(sKey)
if i == -1:
continue
sAlias = AttrLookup[sKey]
pSE.AlterFieldAliasName(sKey, sAlias)
except:
print "Error altering field aliases"
print "Done."
print 'Field <--> Alias lookup table is:', BuildFieldAliasLookup()
print AlterAlias()
