JS/WASM module of NextGraph (SDK and apps) |
||||
|
||||
## NextGraph |
||||
|
||||
> NextGraph brings about the convergence between P2P and Semantic Web technologies, towards a decentralized, secure and privacy-preserving cloud, based on CRDTs. |
||||
> |
||||
> This open source ecosystem provides solutions for end-users and software developers alike, wishing to use or create **decentralized** apps featuring: **live collaboration** on rich-text documents, peer to peer communication with end-to-end encryption, offline-first, **local-first**, portable and interoperable data, total ownership of data and software, security and privacy. Centered on repositories containing **semantic data** (RDF), **rich text**, and structured data formats like **JSON**, synced between peers belonging to permissioned groups of users, it offers strong eventual consistency, thanks to the use of **CRDTs**. Documents can be linked together, signed, shared securely, queried using the **SPARQL** language and organized into sites and containers. |

Object form, made available under the License, as indicated by a |
||||
copyright notice that is included in or attached to the work |
||||
(an example is provided in the Appendix below). |
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object |
||||
form, that is based on (or derived from) the Work and for which the |
||||
editorial revisions, annotations, elaborations, or other modifications |
||||
represent, as a whole, an original work of authorship. For the purposes |
||||
of this License, Derivative Works shall not include works that remain |

||||
this License, each Contributor hereby grants to You a perpetual, |
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable |
||||
copyright license to reproduce, prepare Derivative Works of, |

||||
with the Work to which such Contribution(s) was submitted. If You |
||||
institute patent litigation against any entity (including a |
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work |
||||
or a Contribution incorporated within the Work constitutes direct |
||||
or contributory patent infringement, then any patent licenses |
||||
granted to You under this License for that Work shall terminate |
||||
as of the date such litigation is filed. |
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the |

||||
modifications, and in Source or Object form, provided that You |

(a) You must give any other recipients of the Work or |
||||
Derivative Works a copy of this License; and |
||||
|
||||

||||
attribution notices from the Source form of the Work, |
||||
excluding those notices that do not pertain to any part of |
||||
the Derivative Works; and |
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its |
||||
distribution, then any Derivative Works that You distribute must |

||||
pertain to any part of the Derivative Works, in at least one |
||||
of the following places: within a NOTICE text file distributed |
||||
as part of the Derivative Works; within the Source form or |
||||
documentation, if provided along with the Derivative Works; or, |
||||
within a display generated by the Derivative Works, if and |
||||
wherever such third-party notices normally appear. The contents |
||||
of the NOTICE file are for informational purposes only and |
||||
do not modify the License. You may add Your own attribution |
||||
notices within Derivative Works that You distribute, alongside |
||||
or as an addendum to the NOTICE text from the Work, provided |

||||
reproduction, and distribution of the Work otherwise complies with |
||||
the conditions stated in this License. |
||||

||||
5. Submission of Contributions. Unless You explicitly state otherwise, |
||||
any Contribution intentionally submitted for inclusion in the Work |
||||
by You to the Licensor shall be under the terms and conditions of |
||||
this License, without any additional terms or conditions. |
||||
Notwithstanding the above, nothing herein shall supersede or modify |
||||
the terms of any separate license agreement you may have executed |
||||
with Licensor regarding such Contributions. |
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade |
||||
names, trademarks, service marks, or product names of the Licensor, |
||||
except as required for reasonable and customary use in describing the |
||||
origin of the Work and reproducing the content of the NOTICE file. |
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or |
||||

||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or |
||||
implied, including, without limitation, any warranties or conditions |
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A |

||||
negligent acts) or agreed to in writing, shall any Contributor be |
||||
liable to You for damages, including any direct, indirect, special, |
||||
incidental, or consequential damages of any character arising as a |
||||
result of this License or out of the use or inability to use the |
||||
Work (including but not limited to damages for loss of goodwill, |
||||
work stoppage, computer failure or malfunction, or any and all |
||||
other commercial damages or losses), even if such Contributor |
||||
has been advised of the possibility of such damages. |
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing |
||||
the Work or Derivative Works thereof, You may choose to offer, |
||||
and charge a fee for, acceptance of support, warranty, indemnity, |
