Third-Party Material

Triptych is a source-based collection. Its sources and PDFs quote, transcribe, or incorporate material that the project does not own. The project's CC BY 4.0 license applies only to project-created contributions and does not apply to the third-party or public-domain material described below.

Retained Reusable Source Artifacts

The reusable source library under src/sources/ may retain exact source bytes when an artifact manifest records an affirmative distribution basis. Those bytes keep their own status and are not offered under Triptych's CC BY 4.0 license merely because they are committed beside project-created metadata.

The retained 1871 English City of God texts are normalized derivatives of Project Gutenberg eBooks 45304 and 45305. Marcus Dods edited the edition and is the named translator; George Wilson translated Books IV, XVII, and XVIII, and J. J. Smith translated Books V--VIII. Douglas L. Alley III, Charlene Taylor, Joe C, and the Online Distributed Proofreading Team produced the Gutenberg transcriptions from Internet Archive and Canadian Libraries images. The retained derivatives remove the Gutenberg wrapper, license, trademark references, and marker lines; normalize line endings; and otherwise preserve the transcription between the markers. The transcriber notes disclose punctuation and spelling corrections, so these files are neither facsimiles nor diplomatic transcriptions. The 1871 text is recorded as public domain in the United States; users must determine its status in other jurisdictions.

The retained Patristic Text Archive transcriptions of Severian of Gabala's six homilies In cosmogoniam are governed by their recorded Creative Commons Attribution-ShareAlike 4.0 International License, not Triptych's CC BY 4.0 license. Each source file states that licence in its own header, and the licence was read per file rather than inferred from the archive, whose README records that its files carry different Creative Commons licences. Sever J. Voicu transcribed the Greek from Migne's Patrologia Graeca 56, Paris 1862, and corrected and standardised its spelling, accents, and punctuation to modern editorial standards; Annette von Stockhausen converted the transcription to CTS-compliant PTA TEI and added the biblical references and the annotation of persons, groups, and places. The publisher is the Berlin-Brandenburgische Akademie der Wissenschaften. Reusers must retain that attribution, indicate changes, and satisfy ShareAlike where the licence requires it. The retained derivatives carry the Greek alone: the TEI header, the editors' annotation, the biblical pointers, the manuscript apparatus, and the source printing's page and line breaks are removed, and the retained files are neither facsimiles nor diplomatic transcriptions. Severian's fourth-century Greek and the modern transcription and encoding of it remain distinct rights objects.

The retained Latin Wikisource transcriptions of Migne's Patrologia Latina -- Ambrose's Hexameron (PL 14), Jerome's Liber quaestionum hebraicarum in Genesim (PL 23), Bede's In principium Genesis (PL 91), Alcuin's Interrogationes et responsiones in Genesim (PL 100), Angelomus of Luxeuil's and Remigius of Auxerre's Commentarii in Genesim (PL 115 and PL 131), and Augustine's De Genesi ad litteram (PL 34) -- reproduce printings of 1841 to 1853 that are public domain in the United States. The wiki source of those pages is licensed CC BY-SA 4.0, a condition on the contributors' markup rather than on Migne's text beneath it; the exact wiki bytes are hashed and recorded but not retained, and the retained derivatives carry the printed Latin alone, with every template, link, heading, category, footnote, and column marker removed, together with the University of Zurich Corpus Corporum encoding note that identifies the encoder rather than the text. Those derivatives are transcriptions of a web witness of the printing and not collations against the printed column.

The retained University of Leipzig/OpenGreekAndLatin CSEL 40.1--40.2 TEI files are governed by their recorded Creative Commons Attribution-ShareAlike 4.0 International License, not Triptych's CC BY 4.0 license. The unmodified XML headers identify University of Leipzig (2014), Emanuel Hoffmann's 1899--1900 edition, Jouve for OCR, correction, and encoding, Gregory Crane as principal, and Greta Franzini, Simona Stoyanova, Bruce Robertson, and Uvius Fonticola in the listed project roles. Reusers must retain attribution, indicate changes, and satisfy ShareAlike where the license requires it. The separately manifested figure referenced by the first XML file reproduces a specimen from the 1899 volume and is recorded as public domain in the United States. The underlying historical edition, digital encoding, and support image remain distinct rights objects.

The retained Internet Archive OCR and automated page-number map for The Ante-Nicene Fathers, volume 1, reproduce a Buffalo 1887 publication carrying an 1885 copyright notice. The volume and notice are public domain in the United States, and Internet Archive records the item as not in copyright in that region. The exact uncorrected OCR and generated pagination data are retained as locating and research derivatives; they are not facsimiles, corrected transcriptions, or independent textual witnesses. The Roberts--Rambaut translation and A. Cleveland Coxe's editorial prefaces and bracketed notes retain their public-domain status and are not offered under Triptych's CC BY 4.0 license. OCR errors must not be attributed to the historical translators, and Coxe's editorial matter must not be attributed to Irenaeus.

Liturgical and Scriptural Texts

Scripture, Missal formularies, Orders of Mass, rubrics, chants, and texts from other liturgical books retain the copyright, public-domain status, license, or other legal status of their respective sources and editions.

In particular:

• src/gpt/liturgy/roman-rite/1962/propers/**/propers/retrieved.txt contains focused OCR source extracts and is not offered under CC BY 4.0; and
• the liturgical-text portions of the corresponding propers/verified.md files, document sources, and PDFs are not offered under CC BY 4.0; and
• English translations carried in the calendar mass indexes under src/sources/calendars/**/propers.yaml are recorded per proper with their own rights basis and, where licensed, the notice their licensor requires. The English translation of The Roman Missal, third edition, is copyright the International Commission on English in the Liturgy Corporation. This project has no permission for it, none is recorded anywhere in this repository, and no ICEL text is carried here in whole or in part. The rights position, with its citations, is settled once in src/sources/inventories/liturgical-english-rights-v1.toml; do not carry ICEL text on the strength of anything short of a written grant, and read that record's seeking_a_licence before writing one in even if a grant arrives, because this repository cannot yet express a text that is licensed and not publishable; and
• the English orations recorded in src/sources/inventories/postconciliar-proper-translations-v1.toml are this project's own work, offered under CC BY 4.0 with the project's authorship identified at the point of use. They translate prayers of the ancient Roman sacramentaries — the Veronense, the Old Gelasian, the Hadrianum — which are out of copyright everywhere, and each entry names its witness and states every difference between that witness and the Missal's own text. They are not an approved liturgical translation, they are not derived from ICEL's, and nothing in them may be used for recitation; and
• the English orations recorded in src/sources/inventories/roman-1962-proper-translations-v1.toml, and the transcription of the same book vendored at src/sources/works/eugene-cummiskey/roman-missal-english-laity/, come from The Roman Missal translated into the English language for the use of the laity, first revised edition (Philadelphia: Eugene Cummiskey, 1861). That translation is in the public domain in the United States by publication date; the artifact record states the basis and its jurisdiction. Triptych claims no exclusive right in the wording and does not offer it under CC BY 4.0. It is a nineteenth-century lay hand missal, not an approved liturgical translation, and nothing taken from it may be used for recitation. The Internet Archive text layer the orations were read out of is registered as a remote artifact of that same edition and is not vendored: those exact bytes are a Google-produced derivative carrying Google's own front matter, no distribution grant for it was established, and the record keeps its rights status unresolved.

Their inclusion as evidence or text for study is not a representation that they may be extracted and redistributed independently. Their redistribution status must be established from the governing source and jurisdiction.

Ecclesiastical, Canonical, and Other Official Texts

Magisterial documents, canons, decrees, judgments, diocesan acts, official translations, and other ecclesiastical or civil texts remain subject to their own status. An official character, citation, or public web location does not by itself place a text under the Triptych license.

Received Prayers, Hymns, and Translations

Received prayers, antiphons, chants, collects, hymns, and translations not created by this project are not relicensed. Some historical texts and translations may be public domain in some jurisdictions; where that is so, Triptych claims no exclusive right in the underlying wording. Project-created prayers and translations are CC BY 4.0 only when their project authorship is identified in the adjacent text or source record.

The repository's source records identify, among other examples, traditional English prayer forms and Edward Caswall's 1849 hymn translations as public domain. Users remain responsible for confirming the status applicable to their jurisdiction and intended use.

Quotations and Source Records

Quotations and closely transcribed material from books, articles, websites, surveys, lyrics, prayer books, and other sources remain the property of their respective rights holders where protected. A surrounding source audit, annotation, translation, or synthesis may be project-created without changing the status of the quoted wording.

Received Project Manuscripts

The shared teaching, exercise, reference, and assessment sources under src/gpt/curriculums/ecclesiastical-latin/ derive from a separately supplied Telos project. That donor tree contained no local license. Authorization to integrate and edit the manuscript is not recorded as independent evidence of authorship, ownership, or a general public-distribution license. The prior 52 installed working snapshots received an explicit exact-snapshot distribution exception on 20 July 2026 under the repository's existing user-attested authority. Later exact-current-snapshot exceptions bound corrected files from that same superseded edition. Those bindings remain historical facts about the prior bytes. The redesigned 37-PDF installed edition received a separate exact-current-snapshot distribution exception on 23 July 2026. No exception establishes donor authorship or ownership, supplies a general public-distribution license, or authorizes extracted donor wording outside the exact files it binds. Their course-wide provenance and rights boundary are recorded in the adjacent research/edition-manifest.md, research/scope.md, and research/source-audit.md. No donor manuscript wording is offered under CC BY 4.0 unless a later work-specific rights record establishes that basis.

Fonts and External Software

Published PDFs embed Latin Modern font programs. The altar-server guides and the reading-plan tracks embed Libertinus Serif, Sans, and Mono font programs as used; the tracks were reset in Libertinus on 1 August 2026, having been set in Latin Modern before. Libertinus is supplied by the Libertinus Project and is not relicensed under CC BY 4.0. The installed font metadata identifies SIL Open Font License 1.1; the libertinus TeX support files are supplied separately under the LaTeX Project Public License. The PDFs embed subsetted font programs. TeX packages and other build dependencies are external software governed by their own licenses; they are not vendored merely because the build invokes them.

Reuse and Contributions

Before reusing an excluded passage, consult its citation, the nearby research record, and the original source. Inclusion, citation, or online availability is not a promise of permission for independent reuse.

Contributors must identify third-party material and record its known author, source, attribution, license, permission, public-domain basis, or applicable legal exception. Do not submit material that Triptych is not permitted to distribute.
