  In the pursue for sustainability in process industry, digital twins
necessitate the communication and storage of timeseries data about Industrial
Internet of Things (IIoT). Regarding timeseries, this paper first presents a
set of requirements specific to process industries. Then, it surveys how
existing IIoT technologies meet the requirements. The technologies include the
API specifications Asset Administration Shell (AAS), Digital Twin Definition
Language (DTDL), NGSI-LD and Open Platform Communications Unified Architecture
(OPC UA) as well as six commercial platforms. All the technologies leave
significant gaps regarding the requirements, which means that tailor-made
extensions are necessary.
