Due to key/value stores using JSON objects, the SPARQL resource store can not be used to store them, meaning the only out of the box solution that works is memory storage. This config makes it so file storage can be used for internal storage while still having a SPARQL backend.
This folder contains several configurations that can be used to start up the server.
All those configurations are created in the same way:
features are enabled or disabled by choosing a specific option for every component.
All components are represented by the subfolders found in the folders here:
ldp contains all LDP related components,
identity all IDP components, etc.
Options are then chosen by importing 1 entry from every component subfolder.
In case none of the available options have the exact feature configuration you want,
it is always possible to not choose any of them and create your own custom version instead.
How to use
The easiest way to create a new config is by creating a JSON-LD file
that imports one option from every component subfolder
(such as either allow-all.json or webacl.json from ldp/authorization).
In case none of the available options suffice, there are 2 other ways to handle this:
Append to an existing config
In case the options mostly suffice, but they just need to do a bit more, it might be possible to append to one of the solutions.
For example, in case all the existing metadata parsers can remain,
but an additional one needs to be added,
you could import ldp/metadata-parser/default.json
and then add the following in your root config:
{
"@id": "urn:solid-server:default:MetadataParser",
"ParallelHandler:_handlers": [
{ "@type": "MyNewParser" }
]
}
This will add the new parser to the list of metadata parsers.
Note that generally it is only advised to append to ParallelHandlers or key/value maps. In case the order is important this can not be guaranteed over separate files.
Create a new option
If a more drastic change is required, the solution is to not import anything from that folder but instead write your own.
For example, in case you only want the slug parser but not any of the others,
you would have to not import anything from ldp/metadata-parser folder,
but instead have the following in your root config:
{
"@id": "urn:solid-server:default:MetadataParser",
"@type": "ParallelHandler",
"handlers": [
{ "@type": "SlugParser" }
]
}
Don't forget that in some cases you would also have to copy some imports! The existing options can be used as inspiration.
