Products.ATVocabularyManager 1.6.7

Vocabulary library Plone. Central, Pluggable, TTW, with IMS VDEX Support


  • ATVocabularyManager offers central through the Plone management of dynamic vocabularies.

  • This product is based on Archetypes and made to work with Archetypes as well as with other Products. It is intended use is within Archetypes Fields. Using it as a vocabulary provider for CMFMetadata worked out fine too. Integration with different other products will work as well.

  • to use a managed vocabulary simply add the term vocabulary = NamedVocabulary("myvocabulary") to the fields of your Archetypes Schema, import NamedVocabulary from this Product and create your vocabulary with id myvocabulary in ‘portal_vocabularies’ tool (available through Plone Site-Setup). NamedVocabulary accepts two extra arguments:

    • empty_first_item, needs a boolean for getting an empty item on top of the list, defaults to False;
    • custom_empty_first_item, needs a list of tuple containing a custom first item, defaults to None.
  • ATVocabularyManager supports:

    simple flat key

    value vocabularies

    tree like

    hierachical vocabularies (see Limitations)

    IMS Vocabulary Definition Exchange Format (VDEX) aware vocabularies

    with XML Import and Export. VDEX is i18n-aware by its nature and does not need LinguaPlone!

    Vocabularies are pluggable types.

    ATVocabularyManager is prepared for extension with your special vocabulary type. ArchGenXML will help you here. Each vocabulary term needs to be an CMF aware content type. Reuse normal rich content as a vocabularies.

ArchGenXML 1.4+ code-generator does full integration of ATVocabularyManager: via tagged value defined named vocabularies are registered transparently, VDEX-XML files are imported at install-time, stub vocabularies are created at install time and custom types are registered by just providing appropriate stereotypes.

ATVM is Linguaplone compatible (only tested with SimpleVocabulary, and TreeVocabulary). Add a simple vocabulary with some items, install and configure Linguaplone, translate the vocabulary to the language(s) of your choice, translate every item to the language(s) of your choice. NamedVocabulary() will return the vocabulary as usual, the keys will stay the same disregarding language settings, the values will show in the currently selected language. VDEX vocabularies are not using LinguaPlone, but are i18n-aware (imo much better than everything else).

You can do hierachy-aware searches on treevocabularies (for more information on this see doc/search_treevocabulary.txt) attention: curently certain changes in the term hierachy require a catalog rebuild (see Limitations).


This addon can be installed has any other addons. please follow official documentation

To speed up ATVocabularyManager you might want to associate it with a Cache-Manager.


  • Products.Archetypes
  • imsvdex
  • [Products.Linguaplone] optional


TreeVocabulary catalog updates
If you are using the hierachy-aware catalog search support of tree-vocabularies you need to rebuild the uid_catalog and portal_catalog if you move a vocabularyterm that has other terms below it.
Creation/Edit of VDEX TTW is difficult.
Take an editor of your choice, create the vocab and upload it or help writing an UI.

Known Bugs


Usally the authors are offering professional support. The classical well-working community support is found at the mailing-lists and IRC-channels announced at


Several parts code was created for the ZUCCARO project. ZUCCARO (Zope-based Universally Configurable Classes for Academic Research Online) is a database framework for the Humanities developed by the Bibliotheca Hertziana, Max Planck Institute for Art History For further information: “”:




  • create an issue: simplevocabs do not get alphabetically ordered, nore do they use the order defined by getObjectPositionInParent (see issue #4)
  • drop the try from Products.Archetypes.interfaces.vocabulary import IVocabularyTerm
  • we should add the parameter ‘lang’ to IVocabularyTerm.getTermValue [jens] agrees, but we should make it optional (normally translations should happen transparently)
  • move getTermPath to separate hierarchicalvocabulary interface? [hf] this would allow us to differentiate hierarchical vocabularies by their interface we’d should to make namedvocbaulary.getKeyPathForTerms aware of this too then.
  • (missing in alias) mark methods getVocabularyValue and getVocabularyKey as deprecated and use the methods getTermValue and getTermKey instead [jens] XXX
  • use zope3 interfaces for terms useful for example in NamedVocabulary.getKeyPathForTerms (see comment there)
  • resolve TODOs (XXX, FIXME) marked in the code ;-)

Ideas for features


basic idea:
fields can specify selection depth (0 unlimited, 1 first level, 2 seconde level, etc) that gets displayed in the Displaylist.
why do we need that:
if a certain field does not need the fine-grained selection possibilities a vocabulary offers, no new vocabulary has to be defined.

variable displaylists

basic idea:
field can specify which attribute of the vocabularyterms is used for the displaylist.
why could we need that:
in certain cases the same vocabulary is needed, but another field or field combination should be used for display in the selection.
more complicated handling of cached displaylists (different dictionaries have to be handeled, not just one)

caching displaylists

basic idea:
caching of displaylists and vocabularydicts using ZCacheable (the only thing we’d have to care about is invalidating the cache when a term gets moved or changed)
why do we need that:
fetching vocabulary displaylists costs a lot. at the moment the displaylist for the whole vocab gets fetched everytime a content type that uses the vocabulary is edited and even VIEWED!
[jens] will implement this for the vdex vocabulary in the near future: DONE
open tasks: Invalidate cache after upload of a vdex.
(Auto?)-Assign to a ram-cache-manager.

generic setup support

basic idea
vdex already can be ex and imported to xml. we shoud realize it for simple and term too [jens] decision needed: use vdex, some own xml or better atxml from marshall or just simple Excel importable CSV?) Jens decision is: vdex (implemented import) or csv (todo).


common hierarchic functionality of vdex and tree and possibly other types should be coded in a mixin. code and test once, use everywhere

catalog updates

current limitation:

every change on the structure of a vocabulary (eg: moving a term up the hierarchy) has to trigger not only the invalidation of the cache but also the reindexing of all terms down the hierarchy (uid_catalog search on getTermUidPath, catalog.manage_reindexIndex(ids=(‘getTermUidPath’,)))

currently this is a limitation of treevocabulary. vdex dont need to get cataloged

need to reindex objects in uid_catalog and portal_catalog:
Which method do we need to hook?
in portal_catalog for indexes used by content types

the worse problem is to reindex the objects that define custom indexes on their path-methods. we don’t know which catalog they use (could be portal_catalog, but also any other)


  • store catalog and index in vocab or the atvmtool
  • provide a hook somewhere that can be implemented
  • maybe use references instead of text-linefields to be able to find out which content uses a certain term.

Simple Vocabulary

Simple vocabularies are flat vocabularies.

Creating a simple vocabulary

SimpleVocabularies can be created in the vocabulary library:

>>> portal = layer['portal']
>>> from Products.CMFCore.utils import getToolByName
>>> atvm = getToolByName(portal, 'portal_vocabularies')
>>> from import TEST_USER_ID, setRoles
>>> setRoles(layer['portal'], TEST_USER_ID, ['Manager'])
>>> _ = atvm.invokeFactory('SimpleVocabulary', 'testvocab', title="test vocabulary")

You can fetch a vocabulary calling getVocabularyByName on the vocabulary library

>>> simple = atvm.getVocabularyByName('testvocab')
>>> simple
<SimpleVocabulary at /plone/portal_vocabularies/testvocab>
>>> simple.Title()
'test vocabulary'

Creating simple vocabulary terms

Simple vocabularies can only contain SimpleVocabularyTerms.

>>> simple.allowedContentTypes()
[<FactoryTypeInformation at /plone/portal_types/SimpleVocabularyTerm>]

You can add terms using invokeFactory or the method addTerm:

>>> _ = simple.invokeFactory('SimpleVocabularyTerm', 'term1')
>>> simple.addTerm('term2', 'first time')

addTerm can ignore duplicate keys, and returns whether adding has been successfull.

>>> simple.addTerm('term2', 'second time', silentignore=True)
>>> simple.getDisplayList(portal)
<DisplayList [('term1', ''), ('term2', 'first time')] at ...>

Batch creation

For creating simple vocabularies in python code you can use a convenience method atvm provides for you:

>>> from Products.ATVocabularyManager.utils.vocabs import createSimpleVocabs

This needs to be fed with a dictionary in the following format:

>>> testvocabs = {}
>>> testvocabs['sorting'] = (
...     ('c', u'Alpha'),
...     ('a', u'Zeppelin'),
...     ('y', u'Charly'))
>>> createSimpleVocabs(atvm, testvocabs)
>>> sorting = atvm.getVocabularyByName('sorting')
>>> sorting.contentIds()
['c', 'a', 'y']


You can define the sort order of the vocabularyterms within a simplevocabulary by choosing one of the values in Sort method.

The default sort order is alphabetically by Vales (Title):

>>> sorting.getField('sortMethod').vocabulary.keys()
['getObjPositionInParent', 'lexicographic_values', 'lexicographic_keys']
>>> sorting.getSortMethod()

Sorting by Values

>>> sorting.getDisplayList(portal)
<DisplayList [('c', 'Alpha'), ('y', 'Charly'), ('a', 'Zeppelin')] at ...>

Sorting by keys

>>> from Products.ATVocabularyManager.config import SORT_METHOD_LEXICO_KEYS
>>> sorting.setSortMethod(SORT_METHOD_LEXICO_KEYS)
>>> sorting.getDisplayList(portal)
<DisplayList [('a', 'Zeppelin'), ('c', 'Alpha'), ('y', 'Charly')] at ...>

Sorting by folder position

>>> sorting.listFolderContents()
[<SimpleVocabularyTerm .../sorting/c>, <SimpleVocabularyTerm .../sorting/a>, <SimpleVocabularyTerm .../sorting/y>]
>>> from Products.ATVocabularyManager.config import SORT_METHOD_FOLDER_ORDER
>>> sorting.setSortMethod(SORT_METHOD_FOLDER_ORDER)
>>> sorting.getDisplayList(portal)
<DisplayList [('c', 'Alpha'), ('a', 'Zeppelin'), ('y', 'Charly')] ...>

Linguaplone Support

Simple vocabularies have full Linguaplone Support, but also work w/o having Linguaplone installed:

>>> if portal.portal_quickinstaller.isProductInstalled('LinguaPlone'):
...    portal.portal_quickinstaller.uninstallProducts(['LinguaPlone'])
>>> portal.portal_quickinstaller.isProductInstalled('LinguaPlone')

If Linguaplone is not installed, our vocabulary works without causing troubles

>>> from plone import api
>>> atvm = api.portal.get_tool(name='portal_vocabularies')
>>> createTestVocabulary(atvm)
>>> vocab = atvm.teststates
>>> dict(vocab.getVocabularyDict(vocab))
{'ger': 'Germany', 'fin': 'Finland', 'aut': 'Austria', 'nor': 'Norway'}

If Linguaplone is installed, the simplevocabulary is fully supporting translated vocabularyterms:

XXX go on porting the tests/testSimpleVocabulary testTranslations here


Also sorting on translated vocabularies works as excepted: XXX write tests for the following

  • keys are the same for every language, so sorting by key should result in the same order in every language
  • sorting on title might result in completely differnt order
  • sorting on position in folder might be differnt to, since translations have their separate order

Searches on hierarchical vocabularies

This tests demonstrates how ATVM enables you to make your contenttype searchable using a treevocabulary field.

imagine the following vocabulary:


  • electrical
  • mechanical
    • otto engine
    • diesel engine

a search for engine==mechanical should return all entries for otto and diesel engines

You can skip this tutorial if you are no developer and simply want to learn how to do hierarchy-aware searches on your content type. This is demonstrated in the Product ATVocabularyManagerExample

Setup Vocabulary

let’s create our vocabulary using the utility methods provided by ATVM:

>>> from Products.CMFCore.utils import getToolByName
>>> portal = layer['portal']
>>> atvm = getToolByName(portal, 'portal_vocabularies')
>>> from Products.ATVocabularyManager.utils.vocabs import createHierarchicalVocabs

>>> dictionary = {
...     ('electrical', 'electrical engines'): {},
...     ('mechanical', 'mechanial engines'): {
...        ('otto', 'ottomotor'): {},
...        ('diesel', 'diesel engine'): {}
...     }
... }
>>> hierarchicalVocabs = {}
>>> hierarchicalVocabs[('enginetypes', 'Diffetent types of engines')] = dictionary
>>> from import TEST_USER_ID, setRoles
>>> setRoles(layer['portal'], TEST_USER_ID, ['Manager'])
>>> createHierarchicalVocabs(atvm, hierarchicalVocabs)

now we’ve got our vocabulary available:

>>> engines = atvm.getVocabularyByName('enginetypes')
>>> engines
<TreeVocabulary at /plone/portal_vocabularies/enginetypes>

Background Information

This small section tells you how ATMV achieves that an ottomotor is recognized as a mechanical engine too.

The key of a vocabulary term is the UID of the canonical object (in case the vocabulary is translated into different languages) and can be obtained using the method getTermKey

>>> ottomotor = engines.mechanical.otto
>>> ottomotor.getTermKey() == ottomotor.UID()

A TreeVocabularyTerm implements the method getTermKeyPath that returns a list of vocabularyterm-keys of the term itself and all the terms in the hierarchy above it.

>>> ottoPath = ottomotor.getTermKeyPath()
>>> engines.mechanical.getTermKey() in ottoPath

Each VocabularyTerm is indexed using a KeywordIndex on getTermKeyPath in uid_catalog.

The keypath is is available as a metadata-column in uid_catalog, so it can be fetched for via a catalog query without invoking real objects.

our ottomotor term can be found searching for the ottomotor uid:

>>> uid_catalog = getToolByName(portal, 'uid_catalog')
>>> uid_catalog(getTermKeyPath=ottomotor.UID())[0].getObject()
<TreeVocabularyTerm at .../enginetypes/mechanical/otto>

a search for a machanical engine returns 3 vocabularies: the ottomotor, the dieselengine and the term for mechanicalengine too:

>>> result = uid_catalog(getTermKeyPath=engines.mechanical.UID())
>>> [ for brain in result]
['mechanical', 'diesel', 'otto']

a change in the hierarchy of our vocabulary will reindex all vocabularies below the changed term.

XXX make new term below engines: ‘fossil” and move mechanical there. after that the otto and diesel should be available under fossil too

Make your content type searchable

To be able to search for content types assiciated to terms not only directly but also down the hierarchy we need to index our object under the TermKeyPath(s) of the associated vocabularyterm(s).

ATVM provides a fast implemented utility method for this purpose that is working only on the catalog.

You can utilize getKeyPathForTerms in NamedVocabulary:

>>> from Products.ATVocabularyManager import NamedVocabulary
>>> nv = NamedVocabulary('engines')
>>> keyPath = nv.getKeyPathForTerms(portal, ottomotor.getTermKey())
>>> engines.mechanical.getTermKey() in keyPath
>>> ottomotor.getTermKey() in keyPath

All you need to do is to implement a method that uses the getKeyPathForTerms method and define it as index method:

# .. somewhere in the schemadefinition


# .. somewhere in your content type definition

define someIndexMethod(self):
  """used to index myfield
  # all we have to know is the field name of the field this
  # index method belongs to
  fieldName = 'myfield'

  # the following code need not be touched
  termUID = self.getField(fieldName).get(self)
  return self.getField(fieldName).vocabulary.getKeyPathForTerms(self, termUID)

See ATVocabularyManagerExample for a more detailed explanation how to use ATVocabularyManager in your content type.

  •, configure.zcml,, types/simple/ [rocky]
  • “renamed events” are now fired when the title of any term is updated. [rocky]
  • “deleted events” are now fired when a term is deleted from a vocabulary; this particular feature will only work when running on Zope 2.9 or higher (note: this doesn’t make ATVM dependent on Zope 2.9) [rocky]

  • In Extensions/, self.portal.portal_properties.navtree_properties.metaTypesNotToList is a tuple by default (on a freshly created plonesite) ATVM creates a list at installation time and removes the tool from this list at uninstallation. If other products get installed between installing and uninstalling, they possibly change metaTypesNotToList back to a tuple again. changed the installer and uninstaller to operate on and return a tuple here.
