While crawling directories for data, LuciadFusion also searches for metadata files next to the data files. By default, LuciadFusion
searches for ISO 19139 XML metadata files with the same name as the data file, but with an XML extension. If it finds metadata
files, LuciadFusion monitors them: if the metadata files have been updated, it crawls the directory again, and refreshes the
metadata. If it doesn’t find such metadata files, LuciadFusion generates the metadata based on the TLcdModelMetadata of the data model.
If you want to use your own metadata file format, you must start by implementing the ILcdMetadataDecoder interface and
annotate it as a @LcdService so that LuciadFusion can find you custom decoder. Make sure to override the findAndDecodeMetadata method so that LuciadFusion knows which metadata files to monitor for changes.
The metadata returned from the decoder doesn’t have to be complete. LuciadFusion fills in the missing information
based on the TLcdModelMetadata of the data model for
which the metadata was decoded.
