You are free to:
- Use and reproduce the work for your own purposes
- Modify the work and adapt it into your own projects
- Distribute the work and share it with others
Your freedoms under this license apply
to all copyright
that vests in the work.
You must still ensure that you do not infringe any:
- Patents (unless rights are implied by the licence)
- Neighbouring rights (rights in a sound recording or performance)
- Prohibitions against circumvention of technical protection measures
You may use the work and modify it without sharing your changes, but only if these activities are for your own
personal use. To promote a community of open sharing, you must, however, share your changes with others
under the original licence terms when you:
- Distribute or publicly communicate your modified version to anyone else, whether for free or for profit
- Allow users to interact with or access your modified version of the work, whether over the internet or through another public network
This is a strong copyleft
clause. The copyleft obligation applies to:
- Any adaptation or derivative work you create which is based on the original
but does NOT apply to:
- Any compilation or larger project, as long as it merely includes the whole of the unchanged original work
The licensor makes no guarantee to you as to:
The quality of the work. Keep in mind that the work may contain inaccuracies and errors.
It may be entirely unsuitable for your purpose.
The clearance of rights. It is possible that the licensor might not actually own all of the
rights that the license claims to grant. If this is the case, you could inadvertently infringe the copyright of
a third party -- and you will bear the full responsibility of this infringement.
The license also contains a general disclaimer of liability. In most cases, you cannot sue the
licensor, even if you suffer injuries or financial harm due to errors, inaccuracies, or faults on the part of the licensor.
You must additionally indemnify the licensor for lawsuits that relate to your use of the work.
That is, in certain cases, if someone else sues the licensor, it is still you who must pay for all of the licensor's
legal costs and any damages (even if the licensor is at fault).
Your right to use the work terminates if you breach the terms of the licence is a serious way that amounts to a
"fundametal breach". For smaller mistakes on your part, the licensor can seek monetary damages and other remedies for
any harm done.
Even if the licensor releases a new version of the licence with different terms, you may continue with any
present use of the work under the original terms.
However, if you retrieve an updated copy of the work, it will then come under the terms of the new license.
If a legal dispute arises between you and the licensor, a court at the specific location named in the
license (usually within the jurisdiction of the original licensor) must hear the dispute. If this differs
from your own location, a lawsuit could be more costly for you to pursue or defend.
To resolve any legal disputes, courts will interpret the licence based on the laws in force at the specific
location named in the licence.
