+The first option after calling the website is to either create a new datasheet or to import an existing datasheet. By clicking “Create a new datasheet”, a new document is generated. By clicking “Durchsuchen...” (German) or “Browse...“ (English), a CSV file from the local storage can be loaded into the datasheet.

     Fig. 1: Login to the Datasheet Editor
 
+After clicking on “Create a new datasheet“ or “Durchsuchen...“ / “Browse...“, you will be redirected to the DARIAH-DE log-in, the DARIAH AAI (Authentication & Authorization Infrastructure).

     Fig. 2: Login to the Datasheet Editor with your DARIAH account
 
+Here, you have to log in with your DARIAH account or an eduGAIN federation account. Internally the Geo-Browser and Datasheet Editor are using the DARIAH-DE PDP and OAuth2 tokens for authorization.

+After logging in, a green window with the title “New datasheet created!” opens at the top of the Datasheet Editor. The new datasheet has now an own ID in the DARIAH-DE OwnStorage, with which the sheet can be retrieved again. By using the DARIAH-DE OwnStorage to store your datasets, you can work on a dataset privately until it is complete and working, and then you can share it with the world.

     Fig. 6: Insert new column
 
+By right-clicking on a cell in the datasheet, a row above (“Insert row above”) or below (“Insert row below”) can be inserted. Rows can be removed via “Remove row” and columns via “Remove column”. Columns can be inserted as well either to the left (“Insert column on the left”) or right (“Insert column on the right”). Thus it is possible to create new categories in the datasheet if additional information on the locations is to be saved. Categories can also be altered in the Datasheet Editor.

     Fig. 7: Using geolocation completion
 
+To enter a location directly into the Datasheet Editor, the longitude and latitude must be known. If these data are not already known, the tools on the website “Add geocoordinates“, “Place selection“ and “Map selection“ can be used to find them out. By clicking “Geolocation completion“ in the “Add geocoordinates“ box, the fields “Longitude“, “Latitude“ and “GettyID“ are added automatically for all locations listed in the “Address“ field of the datasheet. These locations will also be listed in the “Place selection“ box.
+
+Here, the Getty Thesaurus of Geographic Names (TGN) is used for searching locations. With TGN larger locations are found, smaller locations are not always found. If the location is not the desired one, in the “Place selection“ box you can click on the arrow next to the location name to open a drop-down menu with a list of other locations with the same name (if they exist). After choosing the correct location from this list, you can click “Set“ right to the drop-down menu to fill in the corresponding fields “Longitude“, “Latitude“ and “GettyID“ in the datasheet.
+
+If the desired location is not listed in the drop-down menu, you can click on the “Map“ field next to it. By this, the location will be entered in the “Map selection“ box, both above and below the world map. Below the world map you can find the search options TGN, OpenStreetMap (OSM) and GeoNames. OSM often also finds smaller locations, which TGN does not find. With OSM it is also possible to find streets and street numbers. By clicking the “Set“ field above the world map, the fields “Longitude“ and “Latitude“ will be updated in the datasheet for the correponding location. Caution: the location entered in the text field above the world map has to be spelled in the same way as the location in the “Address“ field of the datasheet!

     Fig. 8: Manual place and map selection
 
+Another option is to drag the flag in the “Map selection“ box with the mouse, hereby the longitude and latitude can be determined with more precision. By zooming into the map, it’s possible to see streets more precisely. You can also search “manually“ for the places in the datasheet within the “Map selection“ box. But by searching locations via OSM or GeoNames in the “Map selection“ box, GettyIDs will not be given.

+The datasets stored in the OwnStorage are accessible to you only at first. You can read, write, delete, and share each of your datasets. A listing of all your Geo-Browser’s datasets will be available in the near future.

+If you want to share your datasets, you can do so by clicking on “Share dataset“ in the “Manage your data“ box. The dataset shown in the table view will then become available for everyone to read. You can unshare the dataset any time you like. Sharing to and editing with a specific group of people is not yet possible.

+With this action the data from the datasheet can be opened in Geo-Browser. The entered locations are shown as points on the world map. The data is also shown below the world map in a list. If you shared your data, everyone is able to see it in the Geo-Browser. Otherwise, only you can see it.

+As soon as you make an entry in your datasheet, it will be saved (autosave always on). In the datasheet the following data can be entered:
+
+    “Name“: enables you to name your data point. Places have to be entered in the “Address“ field, so “Name“ can be used to display the name of an event or a name that would not be recognized as Address.
+
+    “Address“: identifies the place and is used to add the values for the “Longitude“ and “Latitude“ fields via “Geolocation completion“.
+
+    “Description“: is used to display any additional data.
+
+    “Longitude“: can be filled in by “Geolocation completion“ or manually entered and uses decimal geographic coordinates. Existing coordinates will not be overwritten by “Geolocation completion“.
+
+    “Latitude“: can be filled in by “Geolocation completion“ or manually entered and uses decimal geographic coordinates. Existing coordinates will not be overwritten by “Geolocation completion“.
+
+    “TimeStamp“: is used to store the date of an entry. The format for time stamps is YYYY-MM-DD, however, just naming the year is also possible.
+
+    “TimeSpan:begin“: can be used to convey the beginning of a timespan. Just like “TimeStamp“ it uses YYYY-MM-DD but can be used without specifying the day.
+
+    “TimeSpan:end“: can be used to convey the end of a timespan. Just like “TimeStamp“ it uses YYYY-MM-DD but can be used without specifying the day.
+    
+    “GettyID“: ID for the identification of locations, is automatically filled in using the Getty Thesaurus of Geographic Names via “Geolocation completion“. An existing GettyID will not be overwritten by “Geolocation completion“.
+
+The description of these variables can also be found in the Datasheet Editor by clicking on the “How to fill the table“ button right to the datasheet. It is not required to enter all data to create a datasheet.
