PCA Services is a commercial entity focused on industrial data interoperability. It aims to facilitate sharing of precise data between organizations through projects that apply standardized reference data. Two example projects are ILAP, which uses semantic technology to integrate lifecycle asset planning data across different software tools, and STI, which seeks to standardize definitions and formats for technical information on common equipment in the oil and gas industry. PCA Services provides a reference data library and technical platform to enable broad application of standardized data between domains and systems.
