Markdown does not work in 'Data Quality' field of Geographic Datasets. #308

I use this dataset in CAD:

https://cad.data.gov.bc.ca/dataset/mb-1-6-3-0308-mb

Steps:

  1. Edit the record
  2. Format the Data Quality field

These digital bathymetric maps are derived from two sources which have different data quality factors;

  1. Hand-digitized maps derived from pdf images are scans of the original hand-drawn bathymetric maps; The technology used for the original surveys for these maps is probably the largest data quality consideration. The earliest maps were generated from spot soundings – literally using a weighted line. Subsequent surveys were done using early echo sounding technology and were typically limited to a few transects per lake. The density and accuracy of the sounding points affected the precision and accuracy of the final product. The contours were >also hand interpolated by the draftsperson which is another potential data quality influence.
    Finally, the scanning, digitizing and georectification processes for these map conversions are also all potential error sources. As a result, the digitized versions of original hand-drawn bathy maps tend to be less detailed and potentially of lower accuracy.

  2. Digitally acquired and derived maps are ‘modern’ maps which have been generated using digital X,Y,Z co-ordinates collected with a GPS / depth sounder. The logger collects this data continually while the boat is travelling around the lake. As a result, this data stream tends to be much more dense and widespread. The location and depth data also tends to be of higher accuracy. The data points are interpolated using digital surface (DEM) generating software.
    This surface can then be used to generate bathymetric contours. In short, these types of maps can be expected to be of a higher quality - transcription, projection, interpolation and human drawing errors are reduced or eliminated.

Markdown does not work for the Purpose and Lineage Statement sections also.

@Mbrownshoes I reviewed and edited a number of records in CAD, one for each record type. I found that after my changes, wherever Purpose, Data Quality, and Lineage Statement were present, MarkDown works.

I looked in CAT and verified it does now work, atm. MINFILE Inventory Database (in CAT)

I created the following dataset:

https://cat.data.gov.bc.ca/Geographic/bathymetric-maps-of-surveyed-lakes

Markdown works in the Purpose, Data Quality and Lineage Statement.

I looked at this in PROD and it works correctly. The metadata record brought this bug to our attention was: https://catalogue.data.gov.bc.ca/dataset/bathymetric-maps-of-surveyed-lakes Don Philip contacted us regarding this. I've emailed him informing him that MD in all fields now works correctly.
