It specifies the parameters associated with a positioning module. It does not define any classes but defines the keys that each Positioning Plug-in needs to declare. </p> <p>To use the Positioning Plug-in Information API, a developer must create a Central Repository file with the same UID as the PSY’s UID. This file must contain all the defined keys for the positioning plug-in. If the values for the keys are incorrect the Location Framework will ignore the plug-in and it will not be usable. If this file is to be backed up during a backup operation, the owner of this file should be set to <codeph>0x101f97b2</codeph>, which is the Location Server’s UID. </p> </section> <section id="GUID-3C0DF56B-A650-5FC6-99A4-7A2878280ED2-GENID-1-12-1-19-1-1-10-1-5-1-6-1-2-5"><title>Using the Positioning Plug-in Information API</title> <p>To implement a PSY, the developer must do the following: </p> <ol id="GUID-3BA28F3C-714C-573D-81E5-D87EDCE646CC-GENID-1-12-1-19-1-1-10-1-5-1-6-1-2-5-3"><li id="GUID-DA6F0E1A-A492-571B-AF52-5484526967D0-GENID-1-12-1-19-1-1-10-1-5-1-6-1-2-5-3-1"><p>Create a PSY by implementing the <xref href="GUID-893737B2-4863-5BB9-8AA1-6AB5045FADC9.dita">Positioning Plug-in API</xref>. </p> </li> <li id="GUID-8B9D5ED4-5C91-59FA-A931-A33D1A0FD88B-GENID-1-12-1-19-1-1-10-1-5-1-6-1-2-5-3-2"><p>Create a Central Repository file to publish PSY information according to the Positioning Plug-in Information API. </p> </li> <li id="GUID-A9605241-CFA4-56DA-90FF-968EFD785546-GENID-1-12-1-19-1-1-10-1-5-1-6-1-2-5-3-3"><p>Test the positioning module implementation using the <xref href="GUID-20D774EC-4993-55F5-979C-AF80A264F777.dita">PSY tester application</xref>.
