TEI-IIIF Converter

Introduction

TEI-IIIF turns angle brackets into curly brackets.

To put it in more descriptive terms, it is a Python CLI application that pulls data from TEI XML and transforms to conformant IIIF Annotation manifests, as described in the IIIF Presentation API 3.0.

TEI-IIIF generates a .json manifest for each <div> in a given XML file. Within each <div> it targets <p> elements with a facs attribute, which are used as target values in the output manifests. It uses lxml's etree.tostring method to pull the children of targeted <p> elements, saving them as the value for that given target.

Installation

pip install TEI-IIIF

Basic use

• Settings can be found in settings.yaml. If you have installed tei_iiif in a virtual environment using venv, you can find settings.yaml in your_directory/venv/lib/python[version]/site-packages/tei-iiif.
• Specify the base_url where you are hosting your XML. This can be either a URI (e.g. https://foo.bar/baz/transcriptions/) or a local source (e.g. ./projects/foo-bar/transcriptions/). In both cases, remember the trailing /. Once this has been set, TEI-IIIF can be run from the command line, with the file you wish to convert passed as an argument:

python3 tei_iiif -m transcription.xml

Considerations

• Because TEI-IIIF uses etree.tostring to produce the text for annotations, it captures both tags and text and replicates them. Depending on the input XML, the manifests it outputs may need to be sanitised in order to be used in production, or you may need to sanitise or simplify the XML prior to processing. As use cases can differ dramatically from project to project, TEI-IIIF does not attempt to sanitise output body text.
• However, TEI-IIIF does include regex to sanitise facs attributes such that they use #xywh= formatting for image selectors. This can be changed according to your use case in settings.py
• By default TEI-IIIF assumes you have XML structured in a format roughly equivalent to the following:

<div n="1">
	<p facs=“https://facsimile-server.com/iiif/foo-bar/p1/571,152,1951,1076”>
		<children>...</children>
	</p>
	<p facs="https://facsimile-server.com/iiif/foo-bar/p1/675,728,1949,1320”>
		<children>...</children>
	</p>
</div>
<div n="2">
	<p facs="https://facsimile-server.com/iiif/foo-bar/p2/571,152,1951,1076">
		<children>...</children>
	</p>
	<p facs="https://facsimile-server.com/iiif/foo-bar/p2/675,728,1949,1320">
		<children>...</children>
	</p>
</div>

• If your XML differs dramatically from the below then you can change the XPath in xmlparser.py and divjson.py.
• TEI-IIIF defaults to the base TEI namespace URI. This can be changed in settings.yaml.
