The EVE Online dev team has posted a comprehensive look at the updates coming to the sovereignty system with the Dominion update. Read on!

Hello gang, I'll get right to the point.

As you probably know already, the sovereignty system is getting a new haircut in the Dominion expansion, switching from mohawk to spikes. Relevant API pages have been altered to reflect the change of style. In short, some rowset columns have been removed, one added and one full new page added.

/map/Sovereignty.xml.aspx
This page lists solar systems and their sovereignty information. We've removed constellationSovereignty and sovereigntyLevel and added corporationID. The corporation ID indicates the company which owns the Territorial Claim Unit (TCU) if there is one in the system. We've also lowered the caching time of this page from six hours to one and, since sovereignty changes will happen when they happen (not just during down-time), the age-old problem of out-dated sovereignty information should be a not-so-glorious part of EVE's glorious history.

/map/SovereigntyStatus.xml.aspx
This new page lists all sovereignty structures in EVE in a rowset which has the following columns: structureID, solarSystemID, structureTypeID, ownerID, state, startTime, completionTime. The start- and completion timestamps indicate when the structure's current state began and when it will end. If the state doesn't call for timestamps then they are empty. For a list of all possible states, see the appendix below.

/corp/StarbaseDetail.xml.aspx
This one displays information on a specific station. We've removed claimSovereignty flag.
