TypeError: r is null

[linonetwo]

After I click "Allow" on:

Do you allow creation of 
  /public/tiddlers
  (need r/w access) ?

Console errors: TypeError: r is null and nothing created.

[bourgeoa]

You need to allow read/write to /public/tiddlers with the rainbow pane edit ACL permission

[linonetwo]

Do you mean add https://bourgeoa.solid.community/public/tiddlywiki/ with read/write permission?

[linonetwo]

But I'm the owner of my POD, I should have all permissions.

Update: https://github.com/solid/node-solid-server#upgrading-from-version-4

starting from version 5, third-party apps are untrusted by default. To trust a third-party app, before you can log in to it, you first need to go to your profile at example.com/profile/card#me (important to include the ‘#me’ there), and then hover over the ‘card’ header to reveal the context menu. From there, select the ‘A’ symbol to go to your trusted applications pane, where you can whitelist third-party apps before using them. See also nodeSolidServer/node-solid-server/issues/1142 about streamlining this UX flow.

[bourgeoa]

No in your own solid pod where the app cannot set permission

[linonetwo]

I'm confused, how can I save to my own POD?

[linonetwo]

Where do you think is the line that this Error happened?

[bourgeoa]

Your pod is by default the root of your WebId or the solid pod if you put in one

[bourgeoa]

The information error is in solid-file-widget

[linonetwo]

Can you descript the steps you add permissions?

[linonetwo]

My WebID have full control of my POD, so there should not be permission problem when saving things to my POD if I log in with my WebID.

[bourgeoa]

Go to your pod/public/tiddlers select the rainbow pane and add everybody to owners

[linonetwo]

But there is no /public/tiddlers, do you mean create one by hand first?

I thought it would be created automatically.

[linonetwo]

And I think you should not add everybody to owners. Otherwise, everybody can delete your wiki.

If you login your WebID, you already have all permission in sub-folders.

[linonetwo]

Oh, you should add this to the Readme, after I create that folder manually, this tiddler works.

[linonetwo]

I have full control of /public/tiddlers, but it still not working.

It's not saving things.

[linonetwo]

Should I create a ./main inside /public/tiddlers manually?

[bourgeoa]

Ok I made it work following these steps in a full new solid pod v4.3.1 :

• try to login
• if it says do you allow creation of /public/tiddlers --> refuse
• goto your solid pod and
  ** create /public/tiddlers
  ** in /public allow
  Set the sharing of folder contets separately from the sharing for the folder
  ** in /public/tiddlers add everybody to owners rights
• go back to tiddliwiki and login. It should work

I used chrome browser with both :

• https://bourgeoa.solid.community/public/tiddlywiki/
• https://www.bourgeoa.ga/solidTiddlyWiki/

Whenever you got a 500 error clear the local storage in the browser.
solid server v5.xx as a bug that breaks the synchadaptor syncing

[bourgeoa]

No the creation of folder "/main" is by default if allowed. There seem to be insufficient error tracking Le dim. 14 avr. 2019 à 10:30, lin onetwo <notifications@github.com> a écrit :

I'm using solid-server V5.

So in V5, folder creation is not working, and it's happened in solid-file-widget, am I right?

I may take a look into it.

[bourgeoa]

No in V5 see bug #1170.
You should be able to create the folder but not to create tiddlers due to misuse of encode URI by the server. Saves "Draft%20anything.txt" in lieu of "Draft anything.txt"as exemple. Test and look at a .ttl folder

[bourgeoa]

Happy if you find the origin of the 500 error in solid-file-widget. There is a browser test in /demo

[bourgeoa]

I see you are reworking the app. Nice
I recently come to https://cdn.rawgit.com/abesamma/TW5-editions/78846468/empty.html
With a very interesting concept including a serviceworker's handler for use as a webapp and disconnected.

I have begun some work to convert tiddlers.json to RDF.ttl both ways.
I shall send you that, I hope later today.

I am interested with you intentions with RDF so as to be at least compatible.

[linonetwo]

Hi, I think the ttl can be like this:

index file stores SkinnyTiddlers (without Text tiddler field):

@prefix : <#>.
@prefix pub: <>.
@prefix ldp: <http://www.w3.org/ns/ldp#>.
@prefix terms: <http://purl.org/dc/terms/>.
@prefix XML: <http://www.w3.org/2001/XMLSchema#>.
@prefix tid: <tiddlywiki/>.
@prefix st: <http://www.w3.org/ns/posix/stat#>.
@prefix tur: <http://www.w3.org/ns/iana/media-types/text/turtle#>.
@prefix tiddly: <https://tiddlywiki.com/#>.

<sometiddler.ttl>
    a tur:Resource, ldp:Resource;
    terms:created "2019-05-02T09:37:18Z"^^XML:dateTime;
    terms:modified "2019-05-02T09:37:18Z"^^XML:dateTime;
    st:mtime 1556789838.111;
    tiddly:Title "SomeTitle";
    st:size 1.
<anothertiddler.ttl>
    a tur:Resource, ldp:Resource;
    terms:modified "2019-05-02T09:37:18Z"^^XML:dateTime;
    st:mtime 1556789838.111;
    st:size 1.

We can use https://tiddlywiki.com/# as name space, and describe all tiddler fields in CapitalCamelCase.

So this index file will contains all fields from https://tiddlywiki.com/#TiddlerFields , except the Text field.

What do you think?

[linonetwo]

And actual tiddler is just to add a text field:

@prefix : <#>.
@prefix pub: <>.
@prefix ldp: <http://www.w3.org/ns/ldp#>.
@prefix terms: <http://purl.org/dc/terms/>.
@prefix XML: <http://www.w3.org/2001/XMLSchema#>.
@prefix tid: <tiddlywiki/>.
@prefix st: <http://www.w3.org/ns/posix/stat#>.
@prefix tur: <http://www.w3.org/ns/iana/media-types/text/turtle#>.
@prefix tiddly: <https://tiddlywiki.com/#>.

<>
    a tur:Resource, ldp:Resource;
    terms:created "2019-05-02T09:37:18Z"^^XML:dateTime;
    terms:modified "2019-05-02T09:37:18Z"^^XML:dateTime;
    st:mtime 1556789838.111;
    tiddly:Title "SomeTitle";
    tiddly:Text "asdfasfhusadfupiadshfohdsaoifhoaidshf";
    st:size 100.

I think this is enough for interoperability, and I hope searching and reasoning can be done on those files.

[linonetwo]

Wait, why not just use LDP container as an index file?

[bourgeoa]

Index file is not needed and can be build at run time. I kept it because it was in the model I followed.
for rfd I was proposing a bit more to open the possibility to reuse by non tiddlywiki apps.
See the file join that convert json to ttl. I never endup the way back ttl to json with the fact that tags are multiple.
convertAndBuild1.zip

[linonetwo]

What's the _canonical_uri?

Most vocab you choose is reasonable, much better than what I thought (tiddly:Title and tiddly:Text)

The one I think can improve is "tags":"schema:keywords", I think tag can be represented by http://www.w3.org/1999/02/22-rdf-syntax-ns#type, aka, a

<sometiddler.ttl>
    a tur:Resource, ldp:Resource;
    a <SomeTag.ttl>;

[bourgeoa]

Tag is an index and not a tiddler

[bourgeoa]

_canonical_uri is for example the URL of a external file like music, photos ....

[bourgeoa]

For a structured definition list of tiddlerfields goto https//tiddlywiki.com tag concepts and choose tiddlerfields

[linonetwo]

Ok, sometimes a tag can be another tiddler, while sometimes not.

Maybe just store it as a string of schema:keywords.

Will it be comma separated value?

[bourgeoa]

Yes it is comma separated value

[linonetwo]

Why it's hard to convert back from ttl to json hard? Just parse the CSV then fill in the tags field, isn't it?

[bourgeoa]

Yes but for me parse is not clear. I need example s

[linonetwo]

I didn't think too much, I will just retrieve the object of schema:keywords, and object.split(',')
