2.4.1 Type import and model import

There are two main types of repository content that the system administrator can import into the repository: types and models. There are also two formats, binary patches and XML files, each with their own advantages. Before jumping into exporting and importing, it is worth reading through the rest of this section, plus Section 2.4.3 if you want to update existing instances, and Section 2.4.4 if your modeling language uses static ports.

Types, models or a combination

Type exports (.met, .mxt) include only types, and are made with the Type Manager (see ‘Workbench User’s Guide’). They include graph type generators and all types’ symbols and icons, but not library symbols. Library symbols (.mxs) can be exported from the Symbol Library Browser (see ‘Workbench User’s Guide’). Imports of these will update/overwrite an existing element.

Model exports include instances (design data), either with their types (metamodels) in the binary combo patch (.mec), or without as just models in the XML files (.mxm). Model exports are made with the Graph Manager (see ‘MetaEdit+ User’s Guide'). Imports of instances generally create new instances, but binary patches can also support updating.

Binary patches or XML files

MetaEdit+ binary patches (.met, .mec) can update existing instances (see Section 2.4.3 for how this works), include text formatting and dialog layout, and always include types. Subgraphs can be excluded when exporting.

MetaEdit+ XML files (.mxt, .mxm, .mxs) are in text format, and so can also be edited or created manually. MXM can also import models without affecting types, and import into a different metamodel or MetaEdit+ version.
