+# Jupyter-OpenBIS-extension todos
+
+
+## 1) separate database connection from download/upload dialogue.
+   - Make it a 3rd button
+   - allow only one openBIS-instance (data source) per notebook
+   - after the choice has been made, store the choice in the notebooks' metadata
+   - do not allow to change the data source after that (upload & download)
+   - the reason behind this measure: we need to make sure that we can create a graph
+     of all parent datasets. This is only possible if those datasets origin from the same source.
+   - in future, we might think in terms of workflows that allow data origin from multiple sources.
+
+
+## 2) Download datasets
+   - allow search for experiments by sample code only
+   - paging when a lot of datasets are displayed (>50)
+
+
+## 3) Uploading datasets
+   - let the upload dialog box stay in place until the upload was successful
+   - if metadata is faulty, tell the user to correct them (e.g. invalid vocabulary)
+   - show which metadata is mandatory and which are optional
+   - if dataset type is changed back and forth, keep the values that already have been entered
+   - keep choice of current dataset type
+
+   - show list of downloaded datasets
+   - They should all be parents of the new dataset by default.
+   - User should be able to de-select certain parent datasets
+
+   - show list of files in the current working directory
+   - this list should be served from the jupyter-server-extension,
+     since the user might not be working on his own machine
+   - allow to select one ore many files to upload together with the notebook
+   
+
+## 4) Packaging
+   - pip install --upgrade jupyter-openbis-extension                    # install the jupyter-server-extension
+   - jupyter serverextension enable --py jupyter-openbis-extension      # enable the extension
+   - jupyter nbextension install --py jupyter-openbis-extension --user  # install the nbextension (JS)
+   - jupyter nbextension enable jupyter-openbis-extension --user --py   # activate the nbextension (JS)
+   - try and debug it on a clean machine
+
+## 5) Testing
+   - pytest for jupyter-notebook-extension
+   - test app in different browsers on different platforms (including Windows!)
+
+
+## 6) Details/nice to have: 
+   - change upload (or download) icon: from cloud, to cloud
+   - progression bar or sth to show that it is downloading and doing somehting
+   - more sophisticated forms when uploading datasets
+   - remove remaining jQuery parts to make it easily portable to future Jupyter Lab
