 "summary": "TIGER/Line Files are extracts of selected geographic and cartographic information from the US Census Bureau's Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing (TIGER) system. In the original 2007 specification, internal files had the structure: fe_2007_<extent>_<layer>.<extension> However, from 2008 the naming convention changed to: tl_YYYY_<extent>_<layer>.<extension> Further, TIGER/Line files related to Congressional Districts and Redistricting Data may follow the naming convention: tl_rdYY_<extent>_<layer>.<extension> ‘YYYY’ or ‘YY’ represents the year the data was produced. ‘Extent’ is a 2-5 digit value representing a geographical area. ‘Layer’ specifies the type of geography or feature that the file contains. ‘Extension’ refers to the specific file type, usually .shp, .dbf, .cpg, .shx, or .prj.",
