Open Source Licenses
MIT License
Characteristics: The MIT License is a permissive free software license that allows users to use, copy, modify, merge, publish, distribute, sublicense, and sell copies of the software. The only requirement is that the license and copyright notice must be included in all copies or substantial portions of the software.
Usage: The majority of backend (.NET) and frontend (Angular) components use the MIT license, including:
•All Angular core framework packages (@angular/*)
•Most database providers (Entity Framework, Pomelo MySQL)
•Authentication libraries (JWT, Nebular Auth)
•Utility libraries (Newtonsoft.Json, lodash, rxjs)
Apache License 2.0
Characteristics: Apache 2.0 is a permissive license similar to MIT but includes explicit provisions regarding patent rights. Contributors grant patent licenses to users of the software.
Usage: Used by several key components:
•FluentValidation.AspNetCore (input validation)
•Quartz.Serialization.Json (job scheduling)
•SQLitePCLRaw (SQLite provider)
•TypeScript compiler
•xlsx (Excel parser)
BSD License
Characteristics: BSD (Berkeley Software Distribution) licenses are permissive and similar to MIT with minimal restrictions.
Usage: Used by code editor component ace-builds.
LGPL-2.1 (Copyleft)
Characteristics: The GNU Lesser General Public License is a copyleft license that requires derivative works to be released under the same license. However, it allows linking with proprietary software.
Usage: Used by cytoscape (graph visualization library) in the frontend.
|
Note: LGPL requires that modifications to the cytoscape library itself must be disclosed. Since Raynet One Data Hub uses cytoscape as-is without modifications, no source code disclosure is required. |
