No system of artificial database IDs, but a speaking hierarchy in which the location of a file already says what it refers to. Documents are filed as high as necessary, as precise as possible. The tree # ROOT/ ├── PROPERTIES/ │ └── <property-slug>/ ANCHOR: parcel number │ ├── masterdata.xml │ ├── <documents>.pdf │ └── BUILDINGS/ │ └── <building-slug>/ ANCHOR: coordinates │ ├── masterdata.https://www.prexfo.com/en/docs/format/xml-schema/Mon, 01 Jan 0001 00:00:00 +0000https://www.prexfo.com/en/docs/format/xml-schema/PropertyExchangeFormat — the XML schema # The XML schema defines the DNA of the structured data in Prexfo. It is designed for longevity, flexibility and clarity — not for completeness at any cost.

Prexfo solves this like the successful electronic invoice ZUGFeRD: both live in one file. The principle # A PDF/A-3 document shows the content to the human in the usual form. Embedded in the same document is the machine-readable prexfo.
