T17:22:59 knb-lter-sbc.25.7 Detritus_Biomass_All_Years.csv Online URLs are live Check that online URLs return something true true Succeeded in accessing URL: Create database table Status of creating a database table A database table is expected to be generated from the EML attributes. A database table was generated from the attributes description CREATE TABLE Detritus_Biomass_All_Years_csv(YEAR TIMESTAMP,MONTH TIMESTAMP,DATE TIMESTAMP,SITE TEXT,TRANSECT TEXT,TREATMENT TEXT,QUAD TEXT,SIDE TEXT,SP_CODE TEXT,WET_WT FLOAT,AREA INTEGER,NOTES TEXT,GENUS TEXT,SPECIES TEXT,SIZE TEXT,functional_GROUP TEXT,SURVEY TEXT,KINGDOM TEXT,PHYLUM TEXT,CLASS TEXT,taxon_ORDER TEXT,FAMILY TEXT,GENUS1 TEXT,SPECIES1 TEXT,COMMON_NAME TEXT,Substrate_type TEXT,Mobility TEXT,Growth_morph TEXT); Display some data Display the first row of data One row of data should be displayed Data load status Status of loading the data table into a database No errors expected during data loading or data loading was not attempted for this data entity The data table loaded successfully into a database Number of records check Compare number of records specified in metadata to number of records found in data The expected number of records (1962) was found in the data table.

Future Direction Implement full suite of quality checks Work form current list (Google spreadsheet) Design/specify Metadata Quality Checks with LTER Network Information System developers and Tiger Team Improve community customization Separate quality check configuration from processing logic where possible Engage community through collaborative effort
