# Mapeathor
#### Mapeathor translates your mapping rules specified in spreadsheets to a mapping language.

[Mapeathor](https://morph.oeg.fi.upm.es/tool/mapeathor) is a simple spreadsheet parser able to generate mapping rules in three mapping languages: R2RML, RML (releases on [2014](https://rml.io/specs/rml/) and [2023](https://w3id.org/rml/portal)) and YARRRML. It takes the mapping rules expressed in a spreadsheet and transforms them into the desired language. The spreadsheet template is designed to facilitate the mapping rules' writing, with the aim of being language independent, and thus, lowering the barrier of generating mappings for non-expert users.

## Example
A more detailed explanation is provided in the [wiki](https://github.com/oeg-upm/Mapeathor/wiki).

### First Step: Fill the spreadseet template with the transformation rules
The template has five mandatory sheets, *Prefixes, Source, Subject PredicateObjectMap* and *Functions*. The last one can be left blank in case there are no functions. The spreadsheet can be in XLSX format or a Google Spreadsheet. **Careful!** When using Google Spreasheets, the sharing option must be enabled. Here is an example of the structure of the spreadsheet.

### Second Step: Choose the output language
One of three options can be chosen: R2RML, RML, RML2014 or YARRRML.

### Third Step: Run it!
The easiest way of running Mapeathor is using the [web service](https://morph.oeg.fi.upm.es/demo/mapeathor) and the [Swagger](https://morph.oeg.fi.upm.es/tool/mapeathor/swagger/) instance. For CLI lovers, the service is available as a [PyPi package](https://pypi.org/project/mapeathor/). Detailed instructions for running the tool can be found in the [wiki](https://github.com/oeg-upm/Mapeathor/wiki).
