Content Model Validator

Validate the given Alfresco content model XML against these rules:

Namespace Validation

• Namespace URI must follow the pattern http://www.{company}.com/model/{prefix}/{version}
• Namespace prefix must not collide with reserved Alfresco prefixes: sys, cm, app, usr, act, wcm, wca, lnk, fm, dl, ia, smf, imap, emailserver, bpm, wcmwf, trx, stcp
• Prefix must be lowercase alphanumeric, 2-6 characters

Structure Validation

• Root element must be <model> with name attribute in format {prefix}:modelName
• Must contain <namespaces> with at least one <namespace> declaration
• If types are declared, they must be inside <types> element
• If aspects are declared, they must be inside <aspects> element

Type and Aspect Validation

• Every <type> must have a name attribute in format {prefix}:typeName
• Every <type> should declare a <parent> (default: cm:content or cm:folder)
• Property names must use the model prefix: {prefix}:propertyName
• Property <type> must be a valid Alfresco data type: d:text, d:mltext, d:int, d:long, d:float, d:double, d:date, d:datetime, d:boolean, d:noderef, d:content, d:any, d:category, d:qname, d:locale, d:period

Mandatory Property Enforcement

• FLAG as ERROR any property that uses <mandatory enforced="true">true</mandatory>.
  • Why it breaks: enforced="true" makes ACS fire the IntegrityChecker immediately inside OnAddAspectPolicy, which runs before NodeServiceImpl.addAspect() has written the properties map to the database. The result is a spurious IntegrityException: Mandatory property not set even when the caller passes a fully-populated properties map.
  • Fix: Use <mandatory>true</mandatory> (no enforced attribute). The integrity check is then deferred to beforeCommit, by which time addAspect() has written both the aspect and its properties.
  • Exception: enforced="true" is safe only on properties belonging to types (not aspects), where the property must be supplied at node creation time via the REST API and is never set programmatically after the fact.
