The community value can be used by BGP routers to help make decisions about routes. There are only a very few communities with fixed meaning. Each organization that uses communities picks the values that it will use and assigns the meaning to those values. A community might be used for example to indicate that a route was leaned from a direct customer of some provider. Other customers of that provider might want to prefer that route without consideration of path length (for example). Some of the ISPs have set up systems of community values to communicate information about routes to their customers.
Based on the name of the route map it appears that it is applied to traffic received from a particular peer and assigns the community values. Those community values could be used by other BGP routers within that AS to make decisions, or the community values could be advertised to peers in other ASes to help them make decisions. There is no way for us to know the particular meaning of these communities.
