This paper introduce ideas to build social space for sharing spatial data, information, but also experience with sharing  spatial data. The objective of  4rh way to SDI  is not to build one node or access point for accessing or  collecting spatial information, the objective is to build network of nodes, where every node could be your access point for spatial information.  The  objective of 4rh way to SDI  is not to be alternative of such public initiatives like INSPIRE, GEOSS,  GMESS or UNSDI but to give chance to anybody to profit from formed Global SDI using standards coming from this initiatives and using interoperability rules defined mainly by Open Geospatial Consortium and W3C. The objective of 4rh way to SDI   is not replace such useful initiatives as OpenStreetMap, but to make results of such initiatives  better accessible for everybody. The objective of 4rh way to SDI   is not to remove such solution like Google Map or others, but give some alternative, where on one side people could share information in different environment including for example Google.  The objective of 4rh way to SDI  is to support utilisation of Open Sources, but so called proprietary solution are not excluded from network, key aspect is interoperability. Objective of 4rh way to SDI  is also give chance to share and use spatial information to people, who doesn’t have necessary infrastructure.

The paper describe concept for Sharing Information Inside Communities -  Uniform Resource Management (URM), which support validation, discovery and access to heterogeneous information and knowledge. It is based on utilisation of metadata schemes. The URM models currently also integrate different tools, which support sharing of knowledge. The URM concept was introduced by NaturNet Redime  project as tool for managing of educational context and now is modified for general sharing of information inside of community in c@r project. The concept is now partly implemented as part of Czech metadata portal, Czech portal for United Nation Spatial Data infrastructure and it is also tested in Latvia by BOCS

In recent years, there is much discussion about so called Spatial Data Infrastructure (SDI) development. This is actively discussed at  uropean level (INSPIRE), at national levels, but also globally in the United Nations context (UN SDI). There are technological solutions, but these are in many cases not available for small data providers or for an organization or enterprise, which don’t have their own servers. There is a possibility to use Google technology, but this doesn’t fulfil the requirements of SDI building, which has both institutional and technical aspects. This paper describes so called GeoHosting technology, based on implementing rules for INSPIRE and UN SDI and OGC standards. Described are three basic models: use free - publish free, outsource your data services, use your own solution
