Hello Roads & Highways User and Developer

We are the GIS Team of the Department of Transportation in Canton Aargau, Switzerland. We are currently implementing our road axes into R&H. During this process we came across a number of questions such as

  • What exactly is the purpose of the Edit Log table, what does its content mean?
  • dActivityType domain contains codes up to 7, but we also found codes 9, 12 and 13. What do they mean? Why are they not listed in the domain table?

Does anyone have an explanation?

We are looking forward to your answers and appreciate your help.

The Edit log table contains records with the XML details (EDITDATA field) around edits as they occur within the database. These build the sequence of events that the system can play out and contain details about which user, made what changes and when. It's been beneficial for us at times when trying to evaluate workflows and potential troubleshooting but isn't overly easy to exploit as an audit log. It's a system table that is generally advised as a don't touch but if someone put in some good coding work I am sure it could be exploited for validations, etc.

Here's an example of the XML details

<?xml version="1.0"?>
<RouteEditModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" SchemaVersion="2">
  <RouteEditActivity xsi:type="RetireRouteInfo" LrsId="3ae0f120-7e23-47f2-b70d-3616cee756b4" NetworkId="1" RouteId="TCLETR00914**C" OperationTime="2018-07-03T00:00:00" FirstM="-0" LastM="0.22" IsPerformDownstreamCalibration="true" DoNotApplyEventBehaviors="false" IsUseWholeRoute="false">
    <OverlappedPortions />
    <RetiredPortion OldFromMeasure="0.165" OldToMeasure="0.22" NewFromMeasure="NaN" NewToMeasure="NaN" />
  </RouteEditActivity>
</RouteEditModel>

The ACTIVITYTYPE field within this Edit log table contains values which align with the dActivityType domain. I can't speak to your 12 & 13 values. I can say in our system a 9 = Retire Route. You say yours ends at a 7 so for us an 8 = Reassign Route, 10 = Reverse Route and 11 = Shorten Route. This one piece I can say I've not yet fully figured out. I can say, reviewing REST services of a different agencies R&H data who is at 10.5.1 (which is the same version as us) shows they only have 7 as well (details below) and these don't align with what our values are. My only hunch could be that we began using R&H at version 10.2.2 and did fairly quick upgrades to 10.3.1. We sat there for a couple years and then jumped to 10.5.1 but I can't say whether or not our values differ because they have carried through from earlier versions or not.

I agree with Scott. I could be misremembering but I think it was Will Isley who said the edit log wasn't really meant for human consumption/eyeballs but just for R&H.

As for "Why are they not listed in the domain table?", you should ask esri at the RHUG call tomorrow January 9th.   

For North Carolina we have the following:

Edit Type #

Edit Type Description

1

Create Route

2

Calibrate Route

3

Reverse Route

4

Retire Route

5

Extend Route

6

Reassign Route

7

Realign Route

12

Cartographic Realignment

13

Load Route

Hope this helps.

I'll echo what Ryan mentioned about the edit log.  It's not designed to be consumed by users as they do their work within Roads and Highways and should never be edited manually.
