{"id":"OFL-1.0","title":"SIL Open Font License 1.0","reviewed_on":"2026-09-22","reviewer":"Giray Havur","text_source":"https://raw.githubusercontent.com/spdx/license-list-data/main/text/OFL-1.0.txt","text_retrieved":true,"verdict":"created","summary":"The record models version 1.0 of the SIL Open Font License, the first edition of the standard licence for open fonts. It grants use, study, copying, merging, embedding, modification, redistribution and sale on four conditions: the font is never sold on its own, the notice and the licence travel with every copy, a modified version does not use a reserved font name, and the font software stays under this licence. The model is the one the library's OFL-1.1 record uses. Nothing here is legal advice.","findings":[{"rubric":1,"severity":"info","field":"spdx:licenseId","description":"The file name, the local name of the odrl:Set IRI, the SPDX identifier and the id of this review record are all OFL-1.0. cc:legalcode points at the text the Open Font License site publishes for version 1.0 and dct:source at the SPDX page.","action":"applied"},{"rubric":2,"severity":"info","field":"odrl:target","description":"odrl:target carries dalicc:CreativeWork and dcmitype:Software, the pair the three OFL-1.1 records carry.

The texts differ in wording rather than in effect: 1.0 says \"Standard Version\" where 1.1 says \"Original Version\", its reserved font name rule reaches \"all references stored in the Font Software, such as the font menu name and other font description fields\" where 1.1 narrows it to the primary font name as presented to the users, and 1.0 has no sentence taking documents made with the font out of the reciprocity. SPDX also lists OFL-1.0-RFN and OFL-1.0-no-RFN, the two editions that say whether a font actually declares a reserved font name, exactly as OFL-1.1-RFN and OFL-1.1-no-RFN do for 1.1. Neither is created here; both are left as a queue item. dalicc:variantKind is \"version\", the kind the library gives a record that models an earlier text of a licence it also holds.","action":"none"}],"family":"Fonts and documentation","port_of":null,"variant_kind":"version","variant_of":null,"notes":"Modelled from the SPDX plain text of OFL-1.0 and checked against the Open Font License site.
