The School of Salamanca - The Web Application
This software package provides a XML/TEI-based digital edition environment. It has been developed as the central element of the web presence of the project "The School of Salamanca. A digital collection of sources and a dictionary of its juridical-political language" of the Academy of Sciences and Literature | Mainz, Germany. It is meant to be deployed as an application package within eXist-db and it draws upon a series of further services described in more detail below. The data files as well as other parts of the infrastructure will be published separately.
Technical documentation can be found in <docs/Technical.md> and a description of the API is in <docs/API.md>.
Some of the particular features of this software are the following:
Segmentation of html files: Since the works in our edition are in some cases rather large, for the reading view we can not render them on-the-fly but do so in advance, and in the process we split them into a series of html segments that are dynamically loaded as one scrolls down ("infinite scrolling"). This makes things such as linking and cross-referencing somewhat more complicated and we have spent some effort to compensate for that. (The level at which the segmentation is done is configurable for each work individually via XML processing instructions. In this way, editors exert some measure of control over the size of the resulting chunks of text.)
Citation Links for sections: At all levels of text above and beginning with paragraphs, context menus are provided (indicated by means of "pointing hand" icons) that offer canonical links to the respective passage. These links are subject to a content negotiation mechanism delivering a plaintext, html or rdf (or, if applicable, image) representation of the passage, depending on the requesting client's capacities. (pdf and other formats are on the roadmap.)
Lemmatized fulltext search: The "Salamanca" web application provides a lemma-based search function that, for instance, when searching for "lex" also delivers results containing "leges", "legum", "legibus" etc. We have achieved this with outsourcing the search functionality from eXist-db to a Sphinxsearch server that lemmatizes texts based on a dictionary (which we are continuously improving).
Microservices architecture: Some of the application's functions are implemented as clients requesting data from dedicated services. Navigation between passages relies (in part) on the id service described above, search relies on an OpenSearch-compatible search service, image viewing on an iiif-conforming image and manifest service etc. For the environment that this application expects, see below.
Configuration is concentrated in a single file modules/config.xqm. This file is one of the things you will want to customize when you intend to launch the software yourself. However, at https://www.salamanca.school, the application is also integrated with the following other servers:
- an iiif-conformant image server (iiif image and presentation APIs)
- an any23 service rendering rdf information in a desired serialisation
- a sphinxsearch search server, accessed via an opensearch-compatible php interface
- a wordpress blog
While we consider some aspects of the software sufficiently consolidated and tests to offer them for public review, criticism and re-use, we are well aware that some other areas urgently need to be taken care of. This concerns, among others:
- Improve documentation - inline documentation (code comments) as well as separate description of the app's workings need improvement
- Performance - when we are satisfied with everything, we want to minify js and css code. However, we also have to revise the application more generally in terms of performance. In some cases, caching routines can certainly help (in the case of the rdf lifting service, we have started working on this, but this is not working properly right now.)
- Error handling can certainly be done in a more orderly way.
