IMS Model Merging Description

• Merge models process
• Start situationSource model files ( model A,
  model B) reside in ProjectWise dmg.
• End situation
• Merged model file (model A model B model C)
  is stored in ProjectWise.
• To perform model merging , models A and B
  should be uploaded to EPM-EDM model server,
  merged there and then the result file model C is
  sent back to ProjectWise dmg.
• Description
• The merge operation is considered as updating a
  model. Updating means the addition, deletion or
  change of a part of the existing model. The
  mechanism for model merging is defined by TNO.
  The "EDM Control Servlet", called IMS Servlet B,
  is developed by VTT. It connects to ProjectWise
  database and extracts the specified source model
  files (e.g. model A and model B) from the
  ProjectWise database. The EDM Control servlet
  sends the files and the merging instruction into
  the EDM database. EDM executes the actual
  merge-command. The result file (e.g. model C) is
  created and is exported as a step physical file
  into the ProjectWise database. The source files
  and the result files are always stored into the
  ProjectWise database.
• The merging instructions are given by using a
  merge-form, which is added, as an interface to
  ProjectWise web client.
