| # OpenPLACSP Historical Procurement
|
|
|
| ## Dataset summary
|
|
|
| OpenPLACSP Historical Procurement contains public procurement notices published by contracting authorities hosted on the Spanish Public Sector Procurement Platform. Every published version of a procurement procedure is retained, including deletion markers, rather than reducing each procedure to its latest state.
|
|
|
| The snapshot covers updates from 2 January 2012 through 30 December 2024. It excludes minor contracts, linked documents, and notices published only through external aggregation platforms.

| ## Dataset structure
|
|
|
| The four configurations form a relational historical dataset. `version_id` is the primary key of `versions` and the foreign key used by the other configurations.
|
|
|
| | Configuration | Rows | Description |
|
| | --- | ---: | --- |
|
| | `versions` | 2,993,582 | One row per published state or deletion marker |
|
| | `lots` | 2,080,084 | Lots attached to each published version |
|
| | `cpv_codes` | 8,944,813 | CPV classifications at procedure or lot level |
|
| | `awards` | 3,086,121 | Procedure results, winning parties, and awarded amounts |
|
|
|
| ### Versions

|
| | `folder_id`, `status_code` | Procurement file number and source status |
|
| | `project_name` | Object or title of the procurement project |
|
| | `contract_type_code`, `contract_subtype_code` | Source contract classification codes |
|
| | `estimated_value`, `budget_tax_exclusive`, `budget_total`, `currency` | Published values, budgets, and currency |
|
| | `procedure_code` | Source procurement procedure code |
|
| | `contracting_party_name`, `contracting_party_nif` | Published authority name and Spanish tax identifier |
|
| | `contracting_party_platform_id`, `contracting_party_type_code` | PLACSP authority identifier and source type |
|
| | `buyer_profile_url` | Public buyer-profile URL |
|
| | `source_archive`, `source_member` | Source ZIP archive and ATOM member |
|
|
|
| ### Lots
|
|
|
| | Fields | Description |
|
| | --- | --- |
|
| | `version_id` | Parent version identifier |
|
| | `lot_id` | Lot identifier within the procedure |
|
| | `name` | Lot name or object |
|
| | `budget_tax_exclusive`, `budget_total`, `currency` | Published lot amounts and currency |
|
|
|
| ### CPV codes
|
|
|
| | Fields | Description |
|
| | --- | --- |
|
| | `version_id` | Parent version identifier |
|
| | `lot_id` | Related lot, or null for a procedure-level classification |
|
| | `cpv_code`, `cpv_name` | Common Procurement Vocabulary code and source label |
|
|
|
| ### Awards
|
|
|
| | Fields | Description |
|
| | --- | --- |
|
| | `version_id` | Parent version identifier |
|
| | `result_position`, `winner_position` | Stable positions within the source version |
|
| | `result_code`, `description` | Published result code and description |
|
| | `award_date`, `received_tenders` | Award decision date and number of tenders received |
|
| | `lot_id` | Related lot when the result is lot-specific |
|
| | `winner_name`, `winner_nif` | Published winner name and Spanish tax identifier |
|
| | `award_tax_exclusive`, `currency` | Published award amount excluding taxes and its currency |
|
|
|
| ## Version semantics
|
|
|
| Repeated `atom_id` and `folder_id` values are expected. Each row in `versions` represents a state published at a particular time. A current-state view can be constructed by selecting the greatest non-null `updated_at` for each `atom_id` and retaining deletion markers when the latest row has `is_deleted = true`.
|
|
|
| All configurations use a single `train` split. Random row-level splits would place versions of the same procedure in different partitions and create temporal leakage. Downstream prediction tasks should use time-aware splits and keep all versions of a procedure together.
|
|
|
| ## Processing
|
|
|
| ATOM entries and CODICE elements are normalized into four relational tables. Source values are preserved without currency conversion, inflation adjustment, imputation, or inferred classifications. Linked procurement documents are not included.
|
|
|
| Stable version identifiers are computed from the source ATOM identifier, update timestamp, and deletion state. Parquet files use explicit schemas, Zstandard compression, and shards of at most 250,000 rows.
|
|
|
| ## Quality
|
|
|
| All 17,104,600 rows passed the required-field checks. The snapshot contains 79,140 deletion markers, no null values in required identifiers or relationship keys, and 70 Parquet shards with verified SHA-256 checksums.
|
|
|
| Machine-readable profiles, schemas, quality results, provenance, and checksums are included under `artifacts/`.
|
|
|
| ## Known limitations
|
|
|
| - The snapshot ends on 30 December 2024 and contains no later notices.
|
| - Coverage is not uniform because contracting authorities joined the platform at different times.
|
| - Fields introduced by later CODICE revisions are absent from older records.
|
| - A procedure may appear many times because every published update is retained.
|
| - Monetary values are not converted or adjusted and should not be aggregated across currencies without conversion.
|
| - Published organization names and tax identifiers are source metadata, not independently verified identity data.
|
| - Linked notices and documents may have changed or become unavailable after the snapshot date.
|
|
|
| ## Source and reuse
|
|
|
| The source data was published by the Directorate-General for State Assets through the Spanish Public Sector Procurement Platform and the Spanish Ministry of Finance open-data catalogue. The source describes the records as public information available for reuse. Attribution to the original publisher and the supplied snapshot provenance must be retained in derived releases.
|
|
|
| The card uses `license: other` because the source-specific reuse terms have not been mapped to a standard Hugging Face license identifier. The original publisher remains responsible for the source records; this dataset provides a normalized historical representation.
