I've received a Arcgis layer containing streets, represented by polylines. When I identify a specific street, a large attribute table pops up:

Although I suspect that there are some custom attributes in this table, the majority of the attributes in the table are listed here: http://webapub.sjrwmd.com/arcgis/rest/services/srvc/srRegMapExcnty/MapServer/17
Is there a way to find a description of these attributes? Searching for 'arcgis street attributes/fields/...' does not yield any solutions. Since I'm new to arcgis, I've no idea where to start searching. Searching for some specific attribute names did not yield any results. This external page http://sumo.dlr.de/wiki/Networks/Import/ArcView gave some insights, but only a few attributes are defined there.
Similarly, is there somewhere more information on a polyline? I need to create a graph, exactly like this: Generating graph edge list from polyline and point shapefiles? Although I understand the proposed solution, it seems really error-prone to match points to end-points of edges based on their geographical coordinates. I don't understand why edges are not simply specified by (u,v), where u and v are identifiers of the starting and ending nodes. Two edges (i,j) and (u,v) are then connected if j=u. At least this is how it's done in Openstreet maps.
