tl;dr: CETEIcean lets you display unmodified TEI documents in a web browser! Examples may be found here.
CETEIcean is a Javascript library that allows TEI documents to be displayed in a web browser without first transforming them to HTML. It uses the emerging Web Components standards, especially Custom Elements. It works by loading the TEI file dynamically, renaming the elements to follow the Custom Elements conventions, and registering them with the browser. Browsers that support Web Components will use them to add the appropriate display and behaviors to the TEI elements; other browsers will use fallback methods to achieve the same result.
Because it preserves the full structure and information from your TEI data model, CETEIcean allows you to build rich web applications from your source documents using standard tools like CSS and Javascript.
CETEIcean was inspired by
TEI Boilerplate,
which also displays TEI in the browser, but differs from it in a couple of
important ways. CETEIcean does not rely on an in-browser XSLT transformation,
triggered by an XSLT directive in the source, so no modification to the source XML is
necessary for it to work. Because it follows the Custom Elements standard, the
HTML it produces is valid and there are no possibilities of element name
collisions (like HTML <p> vs. TEI <p> for example).
You can use CETEIcean in your projects just by grabbing the CETEI.js file from the latest release and linking to it in an HTML file like the examples do. Note that you'll want also to grab the example CSS or make your own. If you want to build and play with it on your own, follow the steps below.
This code fetches a TEI file, transforms it into HTML Custom Elements, and places the result in a div with id "TEI".
var CETEIcean = new CETEI()
CETEIcean.getHTML5("URL_TO_YOUR_TEI.xml", function(data) {
document.getElementById("TEI").appendChild(data)
})Returns a Promise that fetches an XML source document then calls the makeHTML5 method on the returned document.
Parameters:
url: The XML document will be fetched from the provided URL.callback: A function to be called on the results.perElementFn: A function to be called on each resulting element.
Converts the supplied XML string into HTML5 Custom Elements.
Parameters:
XML: The XML document serialized to string.callback: A function to be called on the results.perElementFn: A function to be called on each resulting element.
Converts the supplied XML string into HTML5 Custom Elements.
Parameters:
XML_dom: The XML document as DOM.callback: A function to be called on the results.perElementFn: A function to be called on each resulting element.
To change a namespace to prefix mapping, the namespace must first be unset. Takes a namespace URI. In order to process a TEI P4 document, e.g., the TEI namespace must be unset before it can be set to the empty string.
Sets the base URL for the document. Used to rewrite relative links in the XML source (which may be in a completely different location from the HTML wrapper).
Get NodeJS.
Run
npm i
npm run build
puts a copy of CETEI.js in the dist/ folder
npm run dev
runs a local web server on port 8888. Browse to the examples in the test/
folder. Make changes and they'll show up when you reload.
Run the build process and then include the generated CETEI.js file in an HTML
document like the simpleTest.html file in the test/ folder. Or, use the
server-side language and framework of your choice to generate such files on demand.
TEI documents displayed using CETEIcean can be customized via CSS or by specifying behaviors for individual elements. For documentation on behaviors see the wiki.
