Each table's corresponding model contains the full (and most current) details of the schema including default values, indexes and foreign key relationships.

We exclude the following generic Rails columns from the descriptions below since they are common to almost every table:

• id (integer) - Rails' unique identifier for the record
• created_at (datetime) - the datetime the record was created
• updated_at (datetime) - the datetime the record was last updated (via Rails!, some of the Rake tasks and manual DB updates are not reflected here)

The annotations table is used to store a Question's 'Example Answer' and it's question specific guidance (as opposed to themed guidance). The values in this table get displayed on the 'Write Plan' tab. An 'Example Answer' appears directly under the question's answer section. The 'Guidance' will appear on the 1st tab of the Guidance section.

Columns:

• text (text) - The content of the example answer or guidance
• type (integer) - Whether the content is an example_answer or guidance
• org_id (integer) - Foreign key to the org who created the content. Typically the creator of the template or in the case of a cusotmization, the org who is customizing the template
• question_id (integer) - Foreign key to the related question
• versionable_id (string) - A unique id used when versioning the Template

Table that stores a DMP's answers

Columns:

• lock_version (integer) - Used to 'lock' an answer to prevent collisions when multiple users are updating the same plan

• last_access (datetime) - The timestamp of the client's last access to the API
• org_id (integer) - An optional foreign key to an associated Org

This is a table managed by Rails

The table that stores the config/rules for a conditional template question. For example if the user answers 'no' to a question like 'Will you preserve your data' subsequent questions like 'What repository will you deposit your data?' would be hiddden. A question can also trigger an email message for example if the user identified a repository they are going to use, an email could be sent to the repository contact letting them know that a large submission is coming their way.

Columns:

• question_id (integer) - Foreign key to the question that triggers the condition
• number (integer)
• action_type (integer) - Enum value defining whether the trigger is removing questions or emailing
• option_list (text) - the responses to the question that invoke this trigger

Columns:

• name (string) - A name for the group. User's will see this when selecting which sets of guidance they want to see for their Plan

• org_id (integer) - Foreign key to the associated Org

The table that stores 'themed' guidance. Themed guidance is guidance that is tagged to specific themes so that it is displayed next to questions that have the same theme association. For example: "Our University prefers that all biologic data is deposited in the UniBio repository" could be associated to the 'Data Preservation" theme so that it would appear next to any questions with that theme on ANY template.

Columns:

• published (boolean) - Whether or not the guidance will be visible to the user
• text (text) - The content of the guidance
• guidance_group_id (integer) - The associated GuidanceGroup

This table is used to identify specific schemes that various identifiers are derived from (e.g. ORCID, ROR, Shibboleth, etc.). These are used in two primary scenarios: A) when an identifier has a specific pattern and is produced/managed by an external organization like ORCID (e.g. http://orcid.org/0000-0000-0000X) and B) when the identifier has special meaning or association to a service or code within the system and we need to store related information about the relationship it has to an external service (e.g. Shibboleth entityIDs). There are several Rake tasks in lib/tasks that can be used (along with the db/seeds.rb file) to populate some of these common record.

The values in this table must be managed manually. There are no associated UI screens

Columns:

• active (boolean) - whether or not the scheme is active (for use with scenario B outlined above)
• description (string) - a description of the scheme for reference
• context (integer) - Bitflag to tell how the scheme's identifiers are used: authentication (e.g. shibboleth), org identification (e.g. shibboleth or ror), plan identification (forthcoming), user identification (e.g. shibboleth or orcid), contributor identification (e.g. orcid)
• logo_url (text) - The location of the corresponding logo.
• name (string) - The unique name for the scheme
• user_landing_url (string) - The landing page prefix for the identifier which will be prepended to identifiers when we do not have them. For example if the API receives an ORCID for '0000-0000-0000X' without the 'http://orcid.org/'

A polymorphic table that stores various external identifiers used throughout the system. This table replaces the old user_identifiers and org_identifiers

Join table connecting Orgs to their TokenPermissionTypes. This table has no corresponding model.

The primary table that stores information about an organization whether they are a university or a funder.

Managed Orgs are ones that have Administrators. A managed org can have templates, guidance, a logo, contact info, etc. This field replaces the old is_other flag. When a user selects (or types) a new Org from the ROR API, the system will create a new Org record that is un-managed. A super admin can switch the Org to a managed org when necessary, and then promote the user(s) to be org admins.

The org_type bitflag can have any combination of several values. Two of those values though contain special significance with regard to some of the system functionality:

• Funder: Allows the org to create templates and guidance that appear on the public facing 'Funder Requirements' page. They also will appear in the list of 'Funders' the user can select from when creating or updating their Plan. A funder's templates are customizable by other Orgs.
• Institution: This is the standard type used to define a Research Institution. This will ensure the Org appears in the list of 'Research Institutions' the user can select from when creating a Plan.

This table identifies which users are collaborating on a Plan and what their respective access levels are for that Plan.

These records are never actually deleted, their 'active' flag is just set to false. This is to ensure that the relationship to the authors is not lost because that is important historical information. When the active flag is set to false the user will no longer see the Plan on their 'My Dashboard' page. They will still be listed as an author though when others access or download the plan.

The available Roles are:

• Creator: the user who created the plan
• Administrator: someone who has full access to the plan. These users can provide access to other users, edit the plan, add contributors, etc.
• Editor: someone who can edit the plan and its contributors but cannot invite other collaborators
• Commenter: someone who can only comment on the plan's answers
• Reviewer: a special designation for an Org Admin allowing them to comment on the plan within the feedback workflow.

Columns:

• access (integer) - A bitflag representing the user's access permissions
• active (boolean) - Whether or not the user will have access to the Plan in the UI.
• plan_id (integer) - The foreign key to the associated Plan

The primary table for a DMP template.

Warning: there should only be ONE default template. The default template is used when the user creates a Plan and specifies a Research Institution that has no template and Funder who has no template.

Published: When a template is published it becomes available when a user creates a Plan.

If an Org Admin alters a published template, a new version of the template is created. The original published version remains in place and is the one a user receives when creating a new plan until the Admin publishes the new version. There are visual icons on the Templates page to help admins understand when their template is in this state. There can be only ONE published version of a template at any given time.

A plan's template association does not change when versioning of a template occurs. The plan retains the version that was available when they created the template.

You can see which version of a template a plan has at the top of the 'Write Plan' page

If the Org is a funder and any other Orgs have customized the funder's template, then they are notified of the new version and provided with a button and screen to help them transfer over the updated changes into a new version of their custommization.
