[[dido:public:ra:1.2_views:3_taxonomic:4_data_tax:start|return to Data Taxonomy]]

[[dido:public:ra:xapend:xapend.a_glossary:l:ledger]] data is comprised of records containing [[dido:public:ra:xapend:xapend.a_glossary:i:immutable|immutable]] data. Even though the data captured within the ledger is immutable, this does not mean the ledger itself is immutable. The ledger can be updated by adding newer versions of existing data that then point back to the original data. Updates are made by applying transactions to the ledger in a prescribed order.
