OSIsoft is developing data services that expose time series data and asset information. By “data services,” we mean relatively simple services that return time series and non-time series data for both PI points and non-PI data sources. These services will allow you to reference the data of interest using such identifiers as PI tags and AF Element Attributes. You will be able to use these data services to construct high-level business services. This presentation will outline our data service design proposal and show how the services can be easily consumed by even basic web service clients like InfoPath.
As Director of Development for Data Access, Ray Verhoeff oversees development of programmatic access to the PI System infrastructure. Ray began his career with OSIsoft in 1993 as a software engineer and developed the PI System's SQL language implementation. In 1997, he assumed the role of Group Leader for the PI Server for Windows NT and UNIX. Prior to OSISoft, he worked for Champion International and Icotron as a process control engineer. A native of Toronto, Canada, Verhoeff earned a BS in Engineering Science from the University of Toronto in 1981. He completed a Master's Degree in Chemical Engineering at the University of Waterloo in 1983.
