Python wrapper for RDFLib applied to a file system ontology.
stfile lets you use semantics to tag folders and files.
Tag your files:
stf tag path tags [tags ...]
List files by given tags:
stf list tags [tags ...]
Use pip to install stfile
pip install stfile
You can now run the stf
command or import stfile itself to develop your own stuff.
Use stfile to develop your own services. Add a Python script on the config file "config.yml" and attach tags.
services:
my-service:
- <my>:<super_useful_tag>
Every time stfile finds a tag attached to a service executes the script with the same name inside the services/
folder.
A service must implement a action(graph, namespaces, node_path_dictionary)
function.
- graph: A RDFLib Graph instance, contains all current information about the semantic file system
- namespaces: A dictionary containing all registered namespaces inside graph
- node_path_dictionary: Contains information about the nodes in a
node: path
fashion.
All namespaces included in config.yml will be loaded into the graph to offer basic covering for the file system ontology, but more can be added in order to develop services.
If you wish to have a better perspective about the graph
stf show [-h] [-f {n3,xml,pretty-xml,nt}]
Shows whole graph
optional arguments:
-h, --help show this help message and exit
-f {n3,xml,pretty-xml,nt}, --format {n3,xml,pretty-xml,nt}
Format of serialization of graph
stfile lets you write SPARQL queries directly to your graph
stf query [-h] ([-s SELECT [SELECT ...] | -c CONSTRUCT [CONSTRUCT ...]
| -d DESCRIBE [DESCRIBE ...] | -a ASK [ASK ...]]
[-r RAW [RAW ...] | -i INPUT] [-w WHERE [WHERE ...]]
[-o OUTPUT]
Execute raw SPARQL query
optional arguments:
-h, --help show this help message and exit
-s SELECT [SELECT ...], --select SELECT [SELECT ...]
Select query
-c CONSTRUCT [CONSTRUCT ...], --construct CONSTRUCT [CONSTRUCT ...]
Construct query
-d DESCRIBE [DESCRIBE ...], --describe DESCRIBE [DESCRIBE ...]
Describe query
-a ASK [ASK ...], --ask ASK [ASK ...]
Ask query
-r RAW [RAW ...], --raw RAW [RAW ...]
Raw SPARQL query
-i INPUT, --input INPUT
input file
-w WHERE [WHERE ...], --where WHERE [WHERE ...]
Where statement
-o OUTPUT, --output OUTPUT
output file
