eoq3pyecorempl - A model persistance layer for EOQ3 based on pyecore

This is a model persitancy layer (MPL) based on pyecore. This MPL behaves similar to a WorkspaceDomain in EOQ2. A workspace directory containing M2 and M1 models in

• .ecore and .
• *.xml

format is parsed and uploaded to a domain as a workspace model.

Usage

Imports:

from eoq3pyecorempl import PyEcoreWorkspaceMpl

Init and connect the MPL:

mpl = PyEcoreWorkspaceMpl(WORKSPACE_PATH)

Load the workspace directory:

mpl.Load()

Connect to the domain and upload the workspace model:

mpl.Connect(domain)

Accessing a M2 model:

res = domain.Do( Get(Cls("workspacemdbmodel__Resource").Sel(Pth("name").Equ("oaam.ecore"))) )

Accessing a M2 model:

res = domain.Do( Get(Cls("workspacemdbmodel__Resource").Sel(Pth("name").Equ("MinimalFlightControl.oaam"))) )

Accessing the model content:

res = domain.Do( Get(Cls("workspacemdbmodel__Resource").Sel(Pth("name").Equ("MinimalFlightControl.oaam")).Idx(0).Pth("content")) )

See also pyeoq/Test/Eoq3/test_pyecorempl.py for working code.

Workspace

A valid WORKSPACE_PATH could look like

• Meta

  • oaam.ecore

• MinimalFlightControl.oaam

• Library.xml

Subfolders are not mandatory.

Such a workspace directory can be found at pyeoq/Test/Eoq3/testdata/Workspace.
