Aggregation of computerized filiation documents (DFI) files for parcels

Description

**Description** From the files of computerized filiation documents (DFI) produced by the DGFIP, the data.gouv.fr team proposes a new way to access the data, in the form of a single aggregated file. You can find the documentation and all the precautions related to the data in the description of the original dataset. If you have any questions about the content of the data, we invite you to ask your questions about the source dataset. The data are identical to the source data, except for: * the deletion of the column "name of the surveyor" which is anonymized, is always the same and therefore has no use * the column "type of row" which is deleted because we flattened the data so that each row is filled in with a mother plot (column "_mere plot") and daughter plot (column "_fille plot") to facilitate reuse. As a result, the column "line type" is no longer required * the addition of the columns "_mere parcel" and "_fille parcel". In most cases, these columns are filled in with a plot containing a long identifier of the type `323190000A0133` to facilitate joining with other databases such as the Etalab Cadastre data. You can simplify this code to the last 6 characters if you only want the section (2 characters) and the number (4 characters). In other cases, you may encounter two values: "EDNC" for "Extraction from the non-cadastrated domain" and "PDP" for "Passing to the public domain" which are more explicit than an empty value. The identifier used for ‘_mere parcel’ and ‘_fille parcel’ is a composite key (a key consisting of several keys) where: * The first 2 characters are the prefixed letter or section number of 0 if only one character. So A becomes 0A * the last 4 characters are the plot number in the prefixed section of 0 if necessary 133 becoming thus 0133 The data is updated automatically when the source data is updated, and the update code is opened. Data are available in csv and parquet formats. The columns of these files are described in the documentation file.
