Tripper
=======
*Triplestore wrapper for Python providing a simple and consistent interface to a range of triplestore backends.*
[](https://pypi.org/project/tripper)
[](https://emmc-asbl.github.io/tripper/latest/)
[](https://github.com/EMMC-ASBL/tripper/actions/workflows/ci_tests.yml?query=branch%3Amaster)
[](https://zenodo.org/badge/latestdoi/547162834)
Basic concepts
--------------
Tripper provides a simple and consistent interface to a range of triplestore backends.
It strives for simplicity and is modelled after [rdflib] (with a few simplifications).
In Tripper:
* All IRIs are represented by Python strings.
Example: `"http://emmo.info/emmo#Atom"`
* Blank nodes are strings starting with "_:".
Example: `"_:bnode1"`
* Literals are constructed with [`tripper.Literal`][Literal].
Example: `tripper.Literal(3.14, datatype=XSD.float)`
To make it easy to work with IRIs, provide Tripper a set of pre-defined namespaces, like `XSD.float`.
New namespaces can be defined with the [`tripper.Namespace`][Namespace] class.
A triplestore wrapper is created with the [`tripper.Triplestore`][Triplestore] class.
Advanced features
-----------------
The submodules `mappings` and `convert` provide additional functionality beyond interfacing triplestore backends:
- **tripper.mappings**: traverse mappings stored in the triplestore and find possible mapping routes.
- **tripper.convert**: convert between RDF and other data representations.
Documentation
-------------
* Getting started: See the [tutorial](docs/tutorial.md)
* [Discovery of custom backends](docs/backend_discovery.md)
* [Reference manual]
Available backends
------------------
The following backends are currently available, either in Tripper or other packages.
| Backend name | Provided by | Requirements | Comment
| ------------ | ------------ | ----------------------- | -----------------
| rdflib | [tripper] | rdflib | In-memory [rdflib] triplestore supporting all features.
| ontopy | [tripper] | EMMOntoPy | Backend for [EMMOntoPy]. In-memory.
| sparqlwrapper | [tripper] | sparqlwrapper | Generic backend for all triplestores supported by [sparqlwrapper].
| collection | [tripper] | DLite-Python | Backend to a [DLite] collection.
| fuseki | [PyBackTrip] | sparqlwrapper | Backend to [fuseki].
| stardog | [PyBackTrip] | sparqlwrapper,pystardog | Backend to [StarDog].
| graphdb | [PyBackTrip] | sparqlwrapper | Backend to [GraphDB].
Installation
------------
Tripper has by itself no dependencies outside the standard library, but the triplestore backends may have specific dependencies.
The package can be installed from [PyPI] using `pip`:
```shell
pip install tripper
```
In addition you would need to install the requirements for one or more of the backends listed in the table above.
For mappings you would also need to install [Pint].
For example:
```shell
pip install rdflib pint
```
