Motivations

In 2.2 release, only copy/paste XML is suppported for insert. There's no way to upload directly a XML file (metadata file, SLD file, WMC file, GetCapabilities file ...) or a MEF file. This improvement allows users to upload such files through a user-friendly interface (see printscreen below).

Copy / Paste insert mode Single File insert (XML, SLD, WMC...) MEF file Upload

Proposal

  • 1. A user select by radio button which type of insert he would perform
    • 1. Case "Copy/Paste": no changes, metadata.insert service called.
    • 2. Case "File Upload": the user have to choose among two file type to upload
      • mef.import service is called, a specific FileVisitor is used to parse file structure (FileVisitor is a new Interface replacing the Visitor Class)
      • 1. Case "Single File (XML, SLD, WMC...)" :
        • the user have to set parameters as in Copy/Paste case (parameters are the same).
        • once insert performs, a link on metadata inserted is diplayed (by clicking on the id of the new metadata)
        • XMLFIleVisitor is used to handle the file structure.
      • 2. Case "MEF file":
        • no parameters are diplayed. All information are in the file info.xml contained in MEF file.
        • MEFFileVisitor is used to handle MEF file structure (equivalent to the old Visitor Class).

As an extension, this improvement will permit to handle all other specific format to insert, just changing the user interface and adding a new class implementing the new FileVisitor interface. For instance, if the proposal concerning MEF format improvement MEFImprovement is voted, it will be easier to modify MEF module to handle this new format.
