Capture single message MetaData

[Paul Johnston]

Hi All,

I know that I can view the Metadata for a Single message from the GUI SMAT message editor (attached screen shot)

Is there a method I can capture the MetaData (specifically TIME Data ) from a previous days SMAT file via Command line or TCL .

And is it possible to capture the Metadata for a single message and based on a Patient data. eg. Medical Record Number or Patient name

Thanks

Paul,

If you are using file-based SMAT, all of the metadata for the messages is stored in the .idx file in a keyed-list format.  If you are using SMAT Database, the metadata is stored as discrete columns in the database file and the message is stored as a BLOB in a column.  So, you should be able to write Tcl code to extract from either source.

Jim ,

Thank you.  We are using file based SMAT files so I can look at the .IDX files. Any idea on how to match the metadata of a single message from the .MSG file to the .IDX file.  ?

Paul,

Generally, the .idx is used to find a specific message within the SMAT file since the .msg is just one long file that is not delimited between messages.  The .idx file has the offset of where each message starts and its length (as well as all the other metadata).  So, I think the approach would be that you traverse through the .msg file using the .idx file as your guide to pull each message, then interrogate each message for your criteria. At that point, you are already on the specific entry within the .idx file and can simply use the metadata.

Hope that makes sense.
