NASPInet, as it is specified, will be a decentralized publish/subscribe-based data exchange network. There will be no single centralized authority to manage the data publishing and subscribing. Instead, all subscriptions to any published data object (hereafter called “signal”) will be managed by the entity that publishes the data. The NASPInet DB services facilitate and data owners manage the data subscriptions of their published data through NASPInet PGs owned and operated by the data owners. Hence, we are slowly transitioning from the hierarchical “hub-n-spoke” type of an architectural design that comprised of the PMU → substation PDC → control center PDC → super-PDC, to a more distributed architecture consisting of the NASPInet PG and DB that integrate with the PDCs or directly with the PMUs in the field.

Semantic data integration employs a data-centric architecture built upon the standardized model for data publishing and interchange, namely the Resource Description Framework (RDF). The web is represented as a layered architecture which can be navigated through URI. RDF is framework used to describe the resources of web which is understandable by machines. RDF is used an unifying model in semantic web where resources are represented as triplets as Subject, Predicate and Object.. The triples can be represented as URI to identify the resources in Web.
Foundation Fieldbus

7.8.5.2.3.1 Variable AccessTable 7.4 shows the following FMS ser vices that allow the user application to access and change variables associated with an object description. Variable access is used for data publishing and reporting trends. When a variable is either a record or an array consisting of multiple variables, it is possible to transfer it as a whole or only one component assigned with a “subindex.”

Realistically, few producers may currently have the capacity to implement and finance such dynamic quality-(re)assurance on their institutional hardware. Easy-to-use tools (e.g. R packages) to support setting up similar automated routines on cloud-based geocomputation platforms are as needed as solutions for financing curation of, and continued use of computational resources by, such routines beyond the funding periods of the projects that originally developed the data products. To ensure reproducibility and provide permanent links to data published alongside a paper, standards, and regulation of data publishing increased and new journals with respect to data publishing emerged. However, so far, increased requirements regarding documentation or transparency are mainly borne by producers while publishers provide few services regarding e.g. metadata generation or updates. Thus, beyond the perspectives of users, producers, and developers integrated here, additional actors need to be considered. Efforts from all actors involved are essential to ensure the implementation of the approaches presented here and widely improve the availability and accessibility of data quality and provenance information.
