Data Loading in OLE happens via different sets of processes, some of which are internal to OLE and some are available as external APIs for clients to call. Depending on the types of data that needs to be ingested, different processes are used.

Data Type	Format	Process	APIs (http or RESTful)
Financial data for initial setup	.xml & .csv	Liquibase and Impex processes convert the data expressed in .xml and .csv and generate sql that then gets inserted by the OLE db process.	NA
KIM Users, Roles, Responsibilities etc.	.csv	Liquibase process takes the .csv and converts them into sql that gets inserted by the OLE db process.	Rice APIs already exist for roles, creating entities,principals etc.. (Internal at the moment)
Locations	.xml	Polling Service that polls specific directory for location xml files to be ingested. The directory paths are controlled by the following parameter(s) <param name="locations.xml.root.location">${project.home}/locations</param> <param name="locations.xml.pending.location">${locations.xml.root.location}/pending</param> The poller polls every minute and picks up files and moves them to the loaded or problem directories as appropriate. Class responsible:OleLocationsXMLPollerServiceImpl.java	Can be a RESTful API
Patrons	.xml	Polling Service that polls specific directory for Patron xml files to be ingested. The directory paths are controlled by the following parameter(s) <param name="patrons.xml.root.location">${project.home}/patrons</param> <param name="patrons.xml.pending.location">${patrons.xml.root.location}/pending</param> The poller polls every minute and picks up files and moves them to the loaded or problem directories as appropriate. Class responsible:OlePatronsXMLPollerServiceImpl.java	Can be a RESTful API
Circulation Policies	.xml	Polling Service that polls specific directory for circulation policies xml files to be ingested. The directory paths are controlled by the following parameter(s) <param name="circ.xml.root.location">${project.home}/circulation-policies</param> <param name="circ.xml.pending.location">${circ.xml.root.location}/pending</param> The poller polls every minute and picks up files and moves them to the loaded or problem directories as appropriate. Class responsible:OleCircPoliciesXMLPollierServiceImpl.java	Can be a RESTful API
Bibliographic/Holdings/Items	.xml	There are batch processes by which bib/holdings/items can be imported via specific profile.	https://docs.google.com/a/kuali.org/document/d/1pbtM4y5aC-4rB_mY44FeArwmTWVu7fhP47FbpF6JPWo/edit?disco=AAAAAGc599E# (Section 8). The section describes the various APIs that are available for importing bibs/holdings/items.
