Self-Hosted DataHub

Managed DataHub

DataHub allows users to make Posts that can be displayed on the app. Currently, Posts are only supported on the Home Page, but may be extended to other surfaces of the app in the future. Posts can be used to accomplish the following:

• Allowing Admins to post announcements on the home page
• Pinning important DataHub assets or pages
• Pinning important external links

Posts Setup, Prerequisites, and Permissions

Anyone can view Posts on the home page. To create Posts, a user must either have the Create Global Announcements Privilege, or possess the Admin DataHub Role.

Creating Posts

Create Posts Using the UI

To create a post, first navigate to the Settings tab in the top-right menu of DataHub. Once you're on the Settings page, click 'Home Page Posts'. To create a new Post, click '+ New Post'.

DataHub currently supports two types of Post content. Posts can either be of type **Text** or **Link**. Click on "Post Type" to switch between these types.

If you choose the text type, enter the title and description as prompted; if you choose the link type, enter the title and the URL of the link and the address of the image as prompted.

Click 'Create' to complete.

Create Posts Using the GraphQL

There is only one type of Post that can be currently made, and that is a Home Page Announcement. This may be extended in the future to other surfaces.

DataHub currently supports two types of Post content. Posts can either contain TEXT or can be a LINK. When creating a post through GraphQL, users will have to supply the post content.

For TEXT posts, the following pieces of information are required in the content object (of type UpdatePostContentInput) of the GraphQL input (of type CreatePostInput)). TEXT posts cannot be clicked.

• contentType: TEXT
• title
• description

The link and media attributes are currently unused for TEXT posts.

For LINK posts, the following pieces of information are required in the content object (of type UpdatePostContentInput) of the GraphQL input (of type CreatePostInput)). LINK posts redirect to the provided link when clicked.

• contentType: LINK
• title
• link
• media. Currently only the IMAGE type is supported, and the URL of the image must be provided

The description attribute is currently unused for LINK posts.

Here are some examples of Posts displayed on the home page, with one TEXT post and two LINK posts.
