The need to support the legacy output schema has been holding back the development of SHERPA/RoMEO. Removing the legacy option will let us improve the quality of the data and improve performance.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The API is the most heavily used part of the RoMEO service. The level of usage occasionally overloads our servers, which affects the availability of the service. Certain unregistered users account for much of the heavy API usage, and they use it very inefficiently. By insisting that they register for access keys, we will be able to initiate dialogues to eliminate or minimise the difficulties they cause.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>See http://tinyurl.com/RoMEO-API-changes for more information, including a detailed schedule of when the changes will take place and advice on how to move to the current version of the API - V.2.9.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Peter Millington<o:p></o:p></p><p class=MsoNormal>SHERPA Technical Development Officer<o:p></o:p></p><p class=MsoNormal>Centre for Research Communications<o:p></o:p></p><p class=MsoNormal>University of Nottingham, UK<o:p></o:p></p></div>
