Community Installation Considerations

The community web-application registers end-users of the virtual observatory and supports the IVO single-sign-on (SSO) system for control of access to science services. By signing on at a community service with a user-name and password, science users can equip their desktop tools with cryptographic credentials that unlock the science facilities all over the VO.

Users need SSO credentials to access secured VOSpace. They may also need the credentials for specific facilities such as UKIDSS.

Users with "strong" identity certificates issued by well-respected authorities may use them with the community web-application. The community software can issue certificates locally (i.e. it contains a certificate authority) for other users, and this makes the certification process far less painful for the users.

The community web-application is compatible with the AstroGrid VODesktop and Astro Runtime software.
