Directories and Paths

In addition to managing structured data, EVA Netmodeler also manages unstructured content. This is content that EVA Netmodeler cannot process directly, such as documents, images or data files produced by other tools. In this case EVA Netmodeler merely manages the meta data of the content, for example its identity, the owner, access rights to the document, and relationships between the content item and other items in the repository. EVA Netmodeler stores the actual unstructured content items themselves in the file system of the server operating system.

The location of the unstructured content is governed by two corresponding sets of system settings:

• Directory settings, typically named xxxDIR, tell the EVA Netmodeler server application where to store and locate files in the file system
• Web Universal Resource Locator settings, typically named xxxURL, tell the web server where to store and locate files on the web. Note that even though the EVA Netmodeler web server and server applications may run on the same physical server, the web server still needs to be given a URL to locate the files it needs.

EVA Netmodeler manages its two primary kinds of unstructured content separately. These are Documents and Templates.

Settings for Documents

The location of Documents in EVA Netmodeler is controlled by the following pair of settings:

• DefaultSourceDir
  Sets the physical path where all file attachments for the Document and the Picture attribute types are stored.
  The value of this setting must correspond logically with that of the 'SourceURL' setting.
• SourceURL
  Used to generate links to documents or pictures belonging to the Document or Picture type attributes.
  The value of this setting must correspond logically to that of the 'DefaultSourceDir' setting.

Settings for Templates

The location of Templates in EVA Netmodeler is controlled by the following pair of settings:

• DefaultTplDit
  Sets the physical path where all file attachments for the Template attribute type are stored.
  The value of this setting must correspond logically to that of the 'TemplateURL' setting.
• TemplateURL
  Used to generate links to templates belonging to the Template type attributes.
  The value of this setting must correspond logically to that of the 'DefaultTplDir' setting.
