# The PTA as platform for digital critical editions (and beyond)

## The [PTA](https://pta.bbaw.de) in a nutshell

1.  **Publication platform (and tool) for Akademienvorhaben [„Die alexandrinische und antiochenische Bibelexegese in der Spätantike“](https://bibelexegese.bbaw.de)**
2.  Also archive for **editions** (in **all languages**, Christian texts from antiquity have been transmitted) and **translations** – also **retro digitalised editions**
3.  Focus: **critical editions** (with extensive documentation of the manuscript tradition to be able to *evaluate* editorial decissions)
4.  Data is **open access** (CC-BY, CC-BY-SA – some exceptions)
5.  Easy **reuse of data** (data publication <https://github.com/PatristicTextArchive/> + Zenodo; API \[cts, git\])
6.  **Web publication** (with several access routes and some tools)
7.  Using **Standards**: [TEI (P5)](https://tei-c.org/release/doc/tei-p5-doc/en/html/index.html) (*adapted Schema*), [CapiTainS Guidelines](http://capitains.org/) (CTS; structure of files/folders), normdata (annotations).


## Following the [*FAIR principles*](https://www.go-fair.org/fair-principles/) {.smaller}

::: {.callout-warning icon="false"}
## *F*indable

-   for example: machine-readable metadata
:::

::: {.callout-important icon="false"}
## *A*ccessible

-   for example: Website (https://pta.bbaw.de)
-   for example: API (https://pta.bbaw.de/api)
-   for example: data repositories (https://github.com/PatristicTextArchive)
:::

::: {.callout-note icon="false"}
## *I*nteroperable

-   linking with other projects (for example: [Clavis Clavium](https://clavis.brepols.net/clacla/Default.aspx), [Pleiades Gazetter](https://pleiades.stoa.org/))
-   refering to norm data (for example: [Diktyon-IDs for Greek manuscripts](http://www.diktyon.org/en/))
-   using normalized vocabulary (for example: [Dublin Core Metadata Initiative](https://dublincore.org/specifications/dublin-core))
-   using standards (for example: [TEI](https://tei-c.org), [CapiTainS](http://capitains.org/))

::: {.callout-tip icon="false"}
## *R*eusable

-   Open Access
-   well documented (edition guidelines and TEI schema, frontend documentation)

-   authors and works (texts)
-   manuscript descriptions
-   indices (biblical and other references, persons, places)
-   search (fulltext, distance; metadata)
