The MetadataGraph combines data from several experiments on the metadata level and allows an integrated view on the available metadata.
With the metamodeling in place, the raw data of PDL are integrated on the metadata level; no manual effort is required to reconcile the heterogeneities in the physical schemas and structures of the raw data.
The scope of conversion is on the metadata level, i.e., conversion of "empty" forms (list of data elements, no patient-level data).
The findings shown in Figure 3 concur with what de Greef et al. found on the metadata level, where the incidence rate increases at occupancy >80%.
In addition, SemLinker also handles frequent schema evolutions automatically and shields analysis processes operating on the schema metadata level from crashing due to unexpected schema changes.
SemLinker, as a principal integrated component in the PDL architecture, adopts an automatic approach that only operates on the schema metadata level without involving physical transformation of data during integration.
Which means you have to be comfortable trusting the startup with metadata-level visibility into all activity on your home network.
Another common situation is a distinction between metadata-level modelling versus data-level modelling [ 29].
Michael Hayden, the former C.I.A. and N.S.A. director, has said, "We kill people based on metadata".
