Notepad

NB: this currently mainly describes how Solid OS stores data on a Solid Pod.

To create a new notepad at /notepad.ttl, add the following triples into it:

</notepad.ttl#this> a          pim:Notepad .
</notepad.ttl#this> dc:author  </profile/card#me> .
</notepad.ttl#this> dc:created "2019-04-17T08:05:19Z"^^XML:dateTime .
</notepad.ttl#this> dc:title   "Shared Notes" .

Now to indicate that his notepad is empty, add an empty first line to it:

</notepad.ttl#this>  pim:next   </notepad.ttl#this_line0> .
</notepad.ttl#line0> dc:author  </profile/card#me> .
</notepad.ttl#line0> dc:content "" .

Now indicate that this is the last line, set this line’s pim:next to the notepad itself:

</notepad.ttl#line0> pim:next </notepad.ttl#this> .

To add a line to the notepad, for instance ‘first line’, first update the content of the first line, by replacing

</notepad.ttl#line0> dc:content "" .

with

</notepad.ttl#line0> dc:content "first line" .

and then add a new participation-line below it, where the user can type their next line; pick a timestamp, for instance 1555488949899, and add the following triples:

</notepad.ttl#this>            flow:participation </notepad.ttl#id1555488949899> .
</notepad.ttl#id1555488949899> flow:participant   </profile/card#me> .
</notepad.ttl#id1555488949899> ical:dtstart       "2019-04-17T08:05:22Z"^^XML:dateTime .
</notepad.ttl#id1555488949899> ui:backgroundColor "#c0d2fe" .

Note that the first line still is the only line in the document, apart from the participation line. To add a second line, start making proper use of the pim:next attribute, by linking the first line to the second line, and then linking the second line back up to the notepad as a whole. The participation line stays as it is. The result will then look like this:

Main notepad

</notepad.ttl#this> a                  pim:Notepad .
</notepad.ttl#this> dc:author          </profile/card#me> .
</notepad.ttl#this> dc:created         "2019-04-17T08:05:19Z"^^XML:dateTime .
</notepad.ttl#this> dc:title           "Shared Notes" .
</notepad.ttl#this> pim:next           </notepad.ttl#this_line0> .
</notepad.ttl#this> flow:participation :id1555488949899 .
