Community, What is it?

Community, What is it?
The Oxford Dictionary defined it as: 1. Body of people living in one place, district or community. 2. Body of people having religion, ethnic origin, profession etc… in common. 3. Fellowship (community of interest) 4. Commune . 5. Joint ownership or liability.
But there are other questions.
Is it defined as much by people viewing it from the outside as people within it?
Can one community benefit from using their resources to help another?
I would like to use this platform to discuss this concept and see how it evolves. Feel free to post your photos that you feel represent examples of community.
I’ll start it off with this random example of a group that I came across a while ago in a Toronto Park. I think that they called themselves the High Park Percussion Workshop. I think that it definitely qualifies as a community.
I don’t know if it still exists but the coming of warm weather made me think about outside stuff.
