text: **‘EDI message’**(electronic data interchange): a message created and exchanged through 
  the electronic transfer, from computer to computer, of commercial and administrative data 
  using an agreed standard; 
  
  **‘e-PRIOR’**: the service-oriented communication platform that provides a series of web 
  services and allows the exchange of standardised electronic messages and documents 
  between the parties. This is done either through web services, with a machine-to-machine 
  connection between the parties’*back office*systems (*EDI messages*), or through a web 
  application (the s*upplier portal*). The Platform may be used to exchange electronic 
  documents (e-documents) such as electronic requests for services, electronic specific 
  contracts, electronic acceptance of services and electronic invoices between the parties. 
  
  **‘Force majeure’**: any unforeseeable, exceptional situation or event beyond the control of 
  the parties that prevents either of them from fulfilling any of their obligations under the 
  FWC. The situation or event must not be attributable to error or negligence on the part of 
  the parties or on the part of the subcontractors and must prove to be inevitable despite 
  their exercising due diligence. Defaults of service, defects in equipment or material or 
  delays in making them available, labour disputes, strikes and financial difficulties may not 
  be invoked as*force majeure*, unless they stem directly from a relevant case of*force*
  *majeure*;
