Subject: QUESTION: do all apsid's in XCF have to be in WebCGM file?
I've been thinking about the biggest issue facing S1000D in adopting WebCGM 2.0. The HOTSPOT element id attribute cooresponds to the figure level. FIGURE can contain multiple GRAPHIC elements. This is like the GRAPHIC/SHEET relationship in the ATA. That means that the S1000D apsid attribute within the hotspot can point to one of a number of graphics (SHEETs) in the figure. This means that there is potentially a one to many relationship between hotspot elements and WebCGM files. We talked about this a little in Munich, but didn't some to a resolution and it's an issue that keeps bothering Peter. Presumably apsid's are required to be unique across all GRAPHICS within a FIGURE. In WebCGM 2.0, we define apsid as: "The unique identifier of the Application Structure for the given WebCGM file" Does this imply that the identifier has to appear in the given WebCGM file? Consider an XCF with might contain apsid's that span multiple WebCGM files. Would a viewer application fail when it didn't find a match in the current WebCGM file?, or ignore it and not load it into the DOM? As a side note, I don't think anyone in the S1000D community has implemented a HOTSPOT element that contains apsid's spanning multiple GRAPHIC elements, but the potential is there. Ideas?
