Please also note, that a person is allowed to link to multiple contact information instances, hence it expects a list of dictionaries, instead of a single dictionary (which would be valid if only a single link is expected).

77	77	You learned now how a valid JSON-LD for an openMINDS metadata instance looks like and how linkages between openMINDS instances are defined. In the following sections you will learn about the different tools that support you to create your own openMINDS JSON-LD metadata collection.

	140	+For curators of the EBRAINS Data & Knowledge service and users with an EBRAINS account, it is possible to register openMINDS conform metadata into the EBRAINS Knowledge Graph database by using the EBRAINS Knowledge Graph Editor. This editor not only allows the manual registration of openMINDS conform metadata, but also has many project management related features establishing a controlled and secured environment for curating metadata of submitted research products that should be published via the EBRAINS Knowledge Graph database (including the assignment of an EBRAINS DOI if requested).
	141	+
	142	+(% style="text-align: justify;" %)
	143	+To guarantee the latter, the EBRAINS Data & Knowledge service has its own EBRAINS Knowledge Graph Editor environment which reserves the rights of publicly releasing metadata and assigned EBRAINS DOIs via the EBRAINS Knowledge Graph for the members of the curation team. Nonetheless, users with an EBRAINS account can receive access to a separate EBRAINS Knowledge Graph Editor environment through a private Collab in the EBRAINS Collaboratory. All members of such a private Collab can then manually register openMINDS conform metadata through the EBRAINS Knowledge Graph Editor to a restricted space of the Knowledge Graph database that is not accessible to any user outside of the respective Collab. In order to publicly release these privately registered metadata, an official curation request has to be made through the EBRAINS Data & Knowledge service.

	146	+Independent of the different user environments, the EBRAINS Knowledge Graph Editor has the following features to facilitate the manual registration of openMINDS conform metadata:

	149	+(1) Input masks for all openMINDS metadata schemas. New metadata instances can be easily created through an intuitive input mask that validates the user entries already against the respective openMINDS schema.

	151	+(% style="text-align: justify;" %)
	152	+(2) Facilitation of correct linkages between metadata instances. In accordance with the openMINDS metadata models, registered metadata instances can be linked with each other. Establishing these linkages is facilitated by jumping via dedicated properties to new input masks of matching schema types.
	153	+
	154	+(% style="text-align: justify;" %)
	155	+(3) Drop down menus for existing metadata instances. Establishing linkages between instances in accordance with the openMINDS metadata models is further facilitated by providing drop down menus for the dedicated properties for selecting existing instances of matching schema types.
