To provide this full picture from which to make decisions, we needed a way to resolve the spatial data that tools provide in order to synthesize it together. In addition to missing, incorrect, and inconsistent information, there is also the challenge of not being able to use existing spatial patterns to capture the full granularity or specificity of the geospatial descriptions required to capture full and dynamic geometric contexts.\n\nThe Spatial Graph Adapter (SGA) pattern provides us a way to extend the simple identification of geometries and simultaneously assign further descriptions and self-context as well as contextual and relational references to other spatial objects in or surrounding the original entity. For example, not only can we use existing notions say that one surface is adjacent to another, but we have a way to say exactly what type of adjacency and to what extent it is adjacent (more examples in accompanying paper). The SGA has also been implemented for several building industry schemas and our further research is in bringing this and other patterns into full use in a Linked Data Platform (ongoing)."]

has processing error text: [2,"smw-datavalue-wikipage-invalid-title","After several iterations of studying building industry data standards (in particular, GBXML, IFC, and CityGML), we began to map not only terms between them, but also conceptual level indicators. First we capture the main spatial arrangement of geometric elements which are extracted automatically from a spatial instance file. Secondly, the SGA pattern allows us to contextualize additional relationships to capture schema-specific ideas to ultimately be able to ask all the data questions simultaneously. We do acknowledge that in several cases there could be benefits to aligning it with other mereotopological or SIO pattern concepts, but these have not been necessary thus far.\n\nEven if we use a common definition for adjacency, such as where two objects would be touching could be considered adjacent, this fails when we want to know, say what columns or walls are adjacent to a space. It is true that they may be touching some building geometries, but what about the cases where you would have adjacent columns, but they are touching only the open air that define that side of a space (not touching but still on that visual or schema induced boundary)? The SGA pattern allows us to extract this type of information and add it as Attributes or ContextualizedRelations to other objects, solving this issue by being able to, for example, group building elements even as what may seem arbitrary in isolated examples. Schemas produce a wide array of these situations, and even more when we start to translate between them."]

Once this mapping was produced and captured via this pattern, further work was possible and completed in the form of View helper files and all of this is being worked into an operational Linked Data Platform to further enhance open data exchange. \n\nOur work was inspired by ideas from Spatial Information Theory, biomedical research for the Semanticscience Integrated Ontology (SIO), Mereotopology, and geospatial data efforts via the Open Geospatial Consortium (OGC), although these are not the only works regarding spatial descriptions."]
