Resourceshttps://wiki.optimal-systems.de/display/devkolibri/yuuvis+Momentum+-+Flex+Viewer+Service RemarksThere is description for extending the viewer service mentioned to be existing in git (ask Jürgen) - however, the link is missing. Get that documentation and cast it into a tutorial article linked to this viewer service concept article! The link pointing to the "freely available" viewer components, also meant to be in git, is also inoperable or not accessible to anyone outside of team kolibri... → grab and integrate that info. Supported filetypes look nicer when in tables:
The API description lacks information... These sentences are somewhat confusing and should be checked with the PO:
Additionally provided parameters will be passed to the custom viewer. (I believe this should read: any further parameters provided will be passed to the custom viewer) Place links for further reading at the bottom (api-gateway, functional extension - client side, architecture, a still-to-be-written customization tutorial) A tutorial, describing how to integrate the viewer service into an Angular application ist missing. |

Extending the Viewer Service
Hint: This feature is currently only for internal use!
For the description about how to extend the viewer service, see the readme here: GitLab
Outlook: We are working on a new customizing concept that allows us to extend the viewer service with additional components with building and deploying the viewer service itself.
The Viewer Service API
For the viewer to process a request, a path pointing to the file to be displayed must be accessible. The mimeType or size may be omitted here if provided in the Request Header.
