B5.1 relation_pid is mandatory for relations to other TerraLID entities; submission identifiers are replaced by TerraLID IDs
O18 object_authenticity and O18.1 object_authenticity_type are mandatory and have exactly one occurrence
O1 object_collectors and SI10 project_date are recommended; their occurrence constraints have been relaxed to allow legacy data
Version 0.3.4
OO8.1 material_ore_accessibility has the new allowed value "unclear"
Restructuring of B4.3 chemistry_value with addition of B4.3.1 chemistry_value_absolute and renumbering of B4.8 chemistry_relative_value to B4.3.2 chemistry_value_relative
Addition of image file type and maximum file size constraints to AS4.2 assemblage_stratigraphy_diagram, O9 object_photo, and S4.2 sample_location_photo
Addition of examples to SI6.1 site_registry_id and SI6.2 site_registry_name
Correction of an internal link to OP4.3.1 material_pigment_composition_mineral_name
Version 0.3.3
Change Obligation of SI6 site_registry to recommended.
Merging of B4.3 chemistry_icp_isotope into B4.2 chemistry_compound to record values measured e.g. by mass spectrometry but reported as elements rather than isotope together with values reported by isotope
Renumbering of metadata fields B4.4 to B4.8 to B4.3 to B4.7 as consequence of the above change
Addition of new B4.8. chemistry_relative_value to record relative compositional values (e.g. +++, tr, <0.4, bdl = 0.5 wt%)
Improved definition of B4.6 chemistry_uncertainty_sigma
Improved definition of B6.4 lia_ratio_uncertainty_sigma
Version 0.3.1
Addition of new OP3.3 material_pigment_composition_chromophore
Change field type of AS 3.1 assemblage_investigation_unit_type to free text
Change scope of OP4.2 material_pigment_composition_compound to all chemical formulas (or names) and its field type to free text
Version 0.3
Addition of OP5.3 material_pigment_production_details
Refined definition of some metadata
Addition of automatic pdf export of the metadata profile and download button on start page
