About The Revised Electronic Anglo-Saxon Charters
Scholarly origins, diplomatic methodology, infrastructure modernisation, intellectual property framework, and the Universität Zürich digital research platform.
1. The Research Vision & Diplomatic Discourse
ASChart (The Electronic Anglo-Saxon Charters) was established as an innovative digital research pilot funded by the British Academy between March and August 2005. The primary scholarly objective was to pioneer how digital text encoding—specifically customised guidelines of the Text Encoding Initiative (TEI P4)—could unlock the diplomatic structures of early medieval royal and ecclesiastical diplomas.
Early English diplomas followed rigorous rhetorical and legal conventions. Rather than treating charter texts as monolithic blocks of narrative prose, ASChart decomposed each diploma into its functional diplomatic components:
By encoding these elements structurally, researchers can systematically compare regional scriptorium practices (e.g. Worcester vs Rochester), trace chancery drafting evolution across dynasties (Mercian supremacy to the West Saxon kingdom), and explore chronological patterns across three centuries of charter production.
2. Project Origins & Academic Leadership (King's College London, 2005)
The foundational project was conceived, encoded, and directed within the Department of History and the Centre for Computing in the Humanities (CCH, now the Department of Digital Humanities) at King's College London:
Principal Investigator who framed the scholarly vision of charter diplomatic analysis and early medieval legal culture.
Pioneer of digital humanities infrastructure who oversaw the xMod architecture and TEI publishing framework.
Named research fellow who developed the customised TEI P4 XML schema and encoded the pre-900 charter corpus.
Engineered the XML validation pipelines, XSLT transformation routines, and original xMod web publication.
Created the original web user experience, visual layouts, and color-coded formula presentation.
Full-text transcriptions sourced from Sean Miller's digital editions; funded by a competitive British Academy research grant.
The original project operated in close concert with contemporaneous digital scholarship, notably the Prosopography of Anglo-Saxon England (PASE), LangScape (charter boundaries), and The Electronic Sawyer at Cambridge.
3. The Universität Zürich Revised Digital Edition (2026)
Published under the auspices of the Englisches Seminar at the Universität Zürich, The Revised Electronic Anglo-Saxon Charters revitalizes and significantly expands this foundational corpus into an enduring, accessible, and responsive research platform conforming to official UZH Corporate Design 2.10.0 guidelines:
Clean Swiss design standards, UZH corporate blue palette, fluid responsive grid, accessible landmarks, and modern typography ensuring optimal legibility across mobile, tablet, and desktop devices.
Integrated web-font pipeline featuring Source Sans 3 and Junicode (WOFF/WOFF2) for authentic insular letterforms, Old English characters (æ, ð, þ, ƿ, ꝼ, Ᵹ), and medieval Latin scribal suspension marks.
Readers can dynamically toggle highlighting across seven formula categories directly in the text reader, isolating invocations, proems, dispositive words, vernacular bounds, dating clauses, and curses at will.
Normalised SQLite 3 database with FTS5 BM25 search ranking, predictive search-as-you-type, Old English virtual keyboard palette, and faceted filtering across kingdoms, archives, and centuries.
Interactive Chart.js distribution charts where every bar and segment routes directly to filtered charter searches, paired with an OpenStreetMap-based Leaflet map documenting 32 early English scriptoria.
Full internationalisation supporting English (EN), German (DE), French (FR), and Latin (LA), plus 1-click citation export into MLA, MHRA, Harvard, Chicago, BibTeX, Zotero (.ris), and EndNote (.enw).
4. Technical Architecture & Infrastructure Evolution
The technical implementation of the Revised UZH Edition represents a fundamental generational upgrade from the original static archive. While the original King's College London site is preserved in an exact local archive mirror at /aschart/, the Revised Edition introduces an outside-the-webroot, database-backed architecture:
5. Legal Basis & Intellectual Property Framework
The archiving of the original static pilot and the re-architecting of the data into The Revised Electronic Anglo-Saxon Charters have been executed under established international copyright principles, statutory research exceptions, and digital curation best practices:
The core historical charter texts—written in Latin and Old English—were produced between A.D. 604 and 900 by Anglo-Saxon kings, bishops, and royal scribes. Works created over a millennium ago are unconditionally in the Public Domain worldwide. No individual or entity holds copyright over the authentic historical wording of King Alfred, King Offa, or Archbishop Wulfred.
As explicitly acknowledged by the original KCL project, the charter texts derive from Sean Miller's website (Anglo-Saxons.net), which transcribed out-of-copyright nineteenth-century editions by Birch and Kemble. Under established UK copyright jurisprudence (Sawkins v. Hyperion Records Ltd [2005]), EU Directive 2019/790 (Article 14), and Swiss URG Art. 2, the faithful digitisation of public domain textual works does not create a new copyright.
The metadata attributes normalised into our database—such as Sawyer catalogue numbers, dating ranges, indictions, grantor/beneficiary names, and boundary coordinates—are historical facts. Under the fundamental idea/expression dichotomy of copyright law, factual historical data points and philological classifications are not subject to copyright monopoly.
The computational extraction and restructuring of formulaic clauses is protected by explicit statutory research exceptions: UK CDPA 1988 § 29A establishes that computational copying of lawfully accessible works for text and data analysis for non-commercial research is permitted by statute; Swiss URG Art. 24d explicitly legalises the automated analysis of texts and data for scientific research.
Under both CDPA 1988 §§ 29–30 (UK Fair Dealing for research, private study, criticism, and review) and Swiss URG Art. 19 (permitted uses in education and scientific research), universities are legally empowered to utilise, analyse, and present scholarly materials for educational and research advancement, conditioned upon proper attribution.
The original pilot was funded with public research monies from the British Academy. Following server retirements at King's College London, the original site was inaccessible for several years. Rescuing, migrating, and modernising orphaned digital humanities datasets into open, enduring formats is a recognised ethical mandate in digital curation, preventing permanent loss of scholarly heritage.
6. Academic Citation Guidelines
