The goal of tuRtle is to parse or export R data with the Turtle syntax for the Resource Description Framework (RDF). This is a very early version that is being co-developed with the [dataset](https://dataset.dataobservatory.eu/) package.

## Installation

You can install the development version of tuRtle with `remotes::install_github()`:

```{r installation, eval=FALSE}

remotes::install_github("dataobservatory-eu/tuRtle", build = FALSE)

```

## Example

Let us organise statements into a table of *s* subject, *p* predicate and *o* object:

```{r tdfdef, results='asis'}

tdf <- data.frame (s = c("eg:01","eg:02",  "eg:01", "eg:02", "eg:01" ),

                   p = c("a", "a", "eg-var:", "eg-var:", "rdfs:label"),

                   o = c("qb:Observation",

                         "qb:Observation",

                         "\"1\"^^",

                         "\"2\"^^", 

                         '"Example observation"')

                   )

knitr::kable(tdf)

```

The Turtle serialisation is this, written into an `example_file`. The parameter `ttl_namespace = NULL` results in using the default prefixes of the dataset package.

```{r ttl_example}

library(tuRtle)

example_file<- file.path(tempdir(), "example_ttl.ttl")

ttl_write(tdf=tdf, ttl_namespace = NULL, file_path = example_file)

readLines(example_file)

```
