 # Uploader to automate the Upload and Import of Objects in museum-digital via WebDAV

 The purpose of this app will be to allow museums to more simply automate the upload of
-their collection data to museum-digital. It is thus targetted at museums using museum-digital
+their collection data to museum-digital. It is thus targeted at museums using museum-digital
 as a publication platform, while using another collection management system.

 While collection management systems differ, an automatic import to museum-digital works in
-a uniform way. Import data is uploaded via WebDAV, an import is configured using a text file. ([See here](https://de.handbook.museum-digital.info/import/importe-selbst-durchfuehren.html))
+a uniform way. Import data is uploaded via WebDAV, an import is configured using a text file.
+([See here](https://de.handbook.museum-digital.info/import/importe-selbst-durchfuehren.html))

 This part of the automatic importing can thus be solved in a one-fits-all solution here.
 Collection management system-specific export scripts are necessary to present the present
 app with data to upload. The export itself is thus out of the scope of the tool described here.

+## Idea / Very Short Summary / Use Cases
+
+### Automatic Publication from Separate Collection Management System
+
+A museum wants to use museum-digital only for publication, while they use a separate collection
+management system. They want to keep their published collections up to date with their local data.
+Hence, they automate an export from their local program. To upload, they move the data into a
+specified folder. The present application monitors the folder and uploads the data to museum-digital.
+
+### Automating Image Uploads
+
+If a museum produces a lot of digital media files (e.g. lots of scans of books / manuscripts),
+it may become tedious to upload them manually. This becomes an issue all the more if there are
+lots of uncompressed, high resolution files (again, common with scans).
+In this case, it may be useful to use this application to automatically upload the object images
+for import using the `ImageByImport` parser - a.k.a. the matching of image files to objects based
+on their file name according to pre-defined rules.
+

 ## Interface

- A command line interface is sufficient for this application
-
-## Libraries/resources to include
-
- `requests` / HTTP library
- JSON parser
- XML parser (for version/update check)
- WebDAV client: [Python](https://pypi.org/project/webdav4/), [Golang](https://github.com/studio-b12/gowebdav)
-
-Either JSON or XML may also serve to store the config data.
