Features

• Add new JSON options to register a special encoder/decoder for JsonResource
• Add possibility to "reaffect" EStructuralFeatures that are collections. This implies that considering a reference myref for an instance obj, then obj.myref = [*instances] is not allowed. The collection is not replaced per-say, but the collection myref is emptied, and the elements of the collection on the right-side of the affectation are inserted in the myref collection.

Bugfixes

• Fix issue with JSON resources not using to_string(...) for EDataType instances
• Fix issue with multiple re-loading and writing of a resource in the same target file

Miscellaneous

• Deprecate Python 3.7 (needs a special version of lxml)
• Fix/update english of the README.rst

Features

• Add json resource in global registry. The json resource is now registered by default, it's not necessary anymore to explicitly register it
• Add argument passing to Resource instances from a ResourceSet. This feature allows the user to pass arguments to a resource when using get_resources or create_resources from a ResourceSet.

Bugfixes

• Fix issue with file protocol starting with file:/.
• Fix deserialization of boolean in json resources.
• Fix enum literals serialization in json resources. Depending on the "level" where's defined the EnumerationLiteral, the serialization should be different: (1) if serialization happens at the metamodel level, all the internal information of the EnumerationLiteral should be written in the json file, (2) if serialization happens at the model level (a model uses a literal defined in the metamodel it conforms to), the EnumerationLiteral should be serialized only by its name.

Miscellaneous

• Pass from "beta" to "stable".
• Add pypy 3.9 and 3.10 as target test Python VM.
• Fix CHANGELOG.rst.

Bugfixes

• Fix issue with serialization of references in JSON for static metamodels.
• Fix issue with the serialization of EEnum in JSON.
• Fix issue with the computation of eResource for static metamodels.

• Add support for EGeneric super types
• Add alternative MRO computation in some cases
• Add attribute handling in DynamicEPackage
• Add support for item deletion in ordered sets
• Add preservation of order for XMI/JSON serialization and deserialization
• Fix issue with (de)serialization of references in JSON
• Fix missing f-string in JSON resources
• Fix URI.relative_from_me method for resources (de)serialization
• Fix missing import of chain
• Drop Python 3.5 support
• Some performance improvement

Various fix and new features, read the README for more information

Features

• Add first support for EDerivedCollection. The derived collections are
  obtained from many features that are also marked as derived. A derived
  collection does not stores nor gets direct information, instead it fetches
  information from other collection, compute a result and store it. In the
  realisation, a derived collection will inherits from a generic derived
  collection that only proposed an empty implementation. Then, the
  implementation must be manually added.

• Add multi-root support for XMI and JSON resources. XMI and JSON with multiple
  roots can now be serialized and deserialized. Their handling is pretty
  transparent as the addition of a new root goes through the append(...)
  method.

• Add a remove(...) method on resources. This method is pretty much the
  opposite of the append(...) method on resources, it simply remove a
  root from the resource.

Bugfixes

• Exception when a wrong type value was inserted in a reference for generated
  code. The call to the EcoreUtils.isinstance method were raising an
  exception as the last part of the code tries to deal with an unexisting
  methods from the generated class.

• Fix EProxy 'force resolve' for static metamodels. When a proxy is set
  towards a static metaclass, the proxy resolution tries to handle the
  inverse reference list which only exists in the .eClass "level".
  Consequently, when a static metaclass is used, the corresponding EClass
  instance must be used.

Miscellaneous

• Add new module for basic values and collections. This module contains the
  ECollection and EValue classes. These class were formerly in the
  ecore module, but due to further development, it is better to have it
  into a dedicated place. This modification is retrocompatible and invisible
  for existing manual/generated code.

Features

• Add option for specific XMI "type" field serialization. XMI uses a special
  field to encode the type of the element. This field is almost always named:
  xsi:type, but in some cases, xmi:type is used instead. To deal with such
  cases, an option is now available: XMIOptions.OPTION_USE_XMI_TYPE.

Bugfixes

• Add missing 'type' field for XMI href serialization. The 'xsi:type' field is
  required when a crossreference is serialized. This field is used to check if
  the resolved resource has the right type (not really, but it help). This
  field is kinda optional at the moment for PyEcore, but required for Java-EMF,
  otherwise the EMF will not be able to create the right proxy for the
  crossreferenced resource.
