FME Form – Load Multiple Types of Dynamic Readers into One Workspace

fme

This is a follow up to this question:

I am trying to find the a workflow that will define dynamic schema readers from a blank workspace – that is to say, without using the "Generate work space" option.

The "Generate Workspace" option seems to only allow for the definition of one type of type (i.e. format) of reader (such as raster). I am trying to figure out how to load many sorts of dynamic readers (raster, shape file, point cloud) into one workspace. As far as I can tell the "add reader" button on the toolbar will only add a static reader.

This help page should get you going.

The key is to change the Workflow Options to Single Merged Feature Type. Also look at the section on Adding Multiple Readers. There are some options there that might assist you.

If I understand the problem correctly, I think you want to incorporate your county shapefile as a Reader and then execute a Tester transformer against that, then route your job accordingly. Use your published parameter of state name in the tester as one of the test clauses, along with the processed yes/no flag. Here's a quickie I threw together:

enter image description here

This looks for features with a Status = 'Other' in this cities shapefile, then routes according to pass/fail. Now, I think FME is sensitive to the order you put your Readers into the workspace, so if you put this reader in after you already have some others in, the others will get executed first. Try it, you might have to make a new workspace, put this logic in first, then put your other readers in after that to get the read order correct. If you want to kill the job if the query fails, there may be a way to do that with pyfme, or you could route the FAILED feature (when status = Completed already) to a Terminator transformer.

Is there a way to look in body of TAB file and search Definition Table for TYPE parameter ?

!table
!version 300
!charset WindowsLatin1

Definition Table
  File "example.jpg"
  Type "RASTER"
   ...

other types are

Type NATIVE Charset "WindowsLatin1"
...
Type LINKED Charset "WindowsLatin2"  '(database linked table)
...
Type ODBC                            '(database 'live' table)
...
Type ASCII Delimiter 09 Titles Charset "WindowsLatin1"
...
Type XLS Titles Range "Sheet1"
...
Type WKS Titles
...
Type ACCESS TABLE "rdatbln_line" Charset "WindowsLatin1"
...
