SilverStripe importer for Museum Plus

This is an importer to import data-records from museumplus by zetcom. It is implemented as a queued-job for the QueuedJobs Module.

Requirements

• SilverStripe ^4.7
• QueuedJobs Module ^4
• PHP 7.4 or newer

Installation

Install using composer

composer require mutoco/silverstripe-mplus-import 1.x-dev

Project status

This is not a stable release (yet). The API might change and there are still several things todo

API configuration

Use the injector to set your credentials for the Mplus API.

SilverStripe\Core\Injector\Injector:
  Mutoco\Mplus\Api\Client:
    properties:
      BaseUrl: 'https://example.com/endpoint'
      Username: 'username'
      Password: '`MPLUS_PASSWORD`'

Here, an environment variable named MPLUS_PASSWORD is used for the actual password. Make sure you set this environment variable in your system or in your .env file.

Configuring the data-mapping

The ImportEngine class is responsible for importing Mplus Datarecords into SilverStripe DataObjects. You have to configure a mapping from the remote "modules" to DataObjects by adding the following to your configuration (ideally, this is stored in app/_config/mplus.yml or similar):

Mutoco\Mplus\Import\ImportEngine:
  modules:
    ModuleName:
      modelClass: DataObjectClass
      fields:
        Field: Path
      relations:
        RelationName:
          name: Path
          type: ModuleName
          fields:
            RelationField: Path
      attachment: RelationName

In this simplified example, ModuleName stands for a module name in Mplus, eg. Person, Exhibition, Object, etc. Then you specify the mapping for this module. The allowed keys for each Module are:

• modelClass: Fully qualified classname of the SilverStripe DataObject
• fields: Mapping from SilverStripe field names (eg. typically what you have configured for $db) to paths in Mplus. These have to start at the "root" level, eg. nested paths need to be written with dot syntax. Example: AdrContactGrp.ValueTxt
• relations: Mapping from SilverStripe relations to collections in Mplus. Usually, collections in Mplus are either repeatableGroup or moduleReference nodes. The RelationName is the name of the relation in the SilverStripe ORM. Then you set the name (path) and type (name of the referenced module) and optional fields that should be stored with the relation (eg. for many_many_extraFields or similar).
• attachment: If set, an attachment will be stored in this relation. Eg. if you set: attachment: Image, the attachment will be stored as the Image relation on the DataObject.

Assuming you have a DataObject that represents a Person in SilverStripe, with the FQCN MyProject\Person, then your Configuration might look like this:

Mutoco\Mplus\Import\ImportEngine:
  modules:
    Person:
      modelClass: MyProject\Person
      fields:
        Firstname: PerFirstNameTxt
        Lastname: PerLastNameTxt
        PlaceOfBirth: PerPlaceBirthTxt
        PlaceOfDeath: PerPlaceDeathTxt
        DateOfBirth: PerDateFromBeginDat
        DateOfDeath: PerDateToEndDat

Of course, the modules can contain multiple entries, which is necessary for more complex setups with relations. Here's an example:

Mutoco\Mplus\Import\ImportEngine:
  modules:
    Person:
      modelClass: MyProjectPerson
      fields:
        Firstname: PerFirstNameTxt
        Lastname: PerLastNameTxt
        PlaceOfBirth: PerPlaceBirthTxt
        PlaceOfDeath: PerPlaceDeathTxt
        DateOfBirth: PerDateFromBeginDat
        DateOfDeath: PerDateToEndDat
    TextBlock:
      modelClass: MyProject\TextBlock
      fields:
        Text: TextClb
        Author: AuthorTxt
    Exhibition:
      modelClass: MyProject\Exhibition
      fields:
        Title: ExhTitleTxt
      relations:
        Texts:
          name: ExhTextGrp
          type: TextBlock
        Person:
          name: ExhPersonRef
          type: Person

In this example, you can import "Exhibitions", which will also import all related Persons and Text-Blocks (TextBlock isn't a module in Mplus, it's an arbitrarily named Model, so that a mapping in the relation is possible at all).

Configuring the import job

To tell the ImportJob which records to import, configure an initial search to get the records to import. The following config would import the Exhibitions with ID 1 and 2.

The search configuration is pretty much an YML to XML mapping of the Mplus Search API.

Mutoco\Mplus\Job\ImportJob:
  imports:
    Exhibition:
      search:
        or:
          - type: equalsField
            fieldPath: __id
            operand: 1
          - type: equalsField
            fieldPath: __id
            operand: 2
