Controlled vocabularies

AnnouncementSourceEnum

The evidence tier the announcement_date came from, in DESCENDING trust. It travels with the value so a buyer can weight or exclude the weaker tiers themselves rather than take a single date on faith.

valuemeaning
disclosedA publication date stated by the issuer or the exchange. Strongest.
http_last_modifiedThe Last-Modified header served for the filing URL.
pdf_creation_dateThe filing PDF's own /CreationDate metadata. Weakest of the three.

EntityStatusEnum

Whether the entity is currently operating, as last observed.

valuemeaning
activeOperating and current at the last observation.
inactiveDissolved, delisted, merged away or otherwise no longer operating.
unknownNo status evidence held. Not a synonym for inactive.

EntityTypeEnum

What kind of thing the entity is. `natural_person` is deliberately ABSENT: natural persons are never published in Certvas entity tables, and the published tender views filter them out under a Soda check. Omitting the value from the vocabulary makes that structural rather than a rule someone has to remember.

valuemeaning
companyA legally incorporated company.
fundA collective investment vehicle.
gov_bodyA government body, agency or state organ.
otherA legal entity that is none of the above.

IdentifierTypeEnum

The identifier scheme a value belongs to.

valuemeaning
tickerAn exchange ticker symbol. Only unique together with exchange_mic.
isinISO 6166 International Securities Identification Number.
figiOpenFIGI Financial Instrument Global Identifier.
cikSEC EDGAR Central Index Key.
registryA national company-registry number.
otherA scheme none of the above covers.

PartyRoleEnum

The role a party plays in a procurement process.

valuemeaning
buyerThe contracting authority.
supplierA party awarded a contract.
bidderA party that bid without (yet) being awarded.

PartyTypeEnum

What kind of party this is. `natural_person` EXISTS here but is filtered out of every published view — sole traders genuinely appear in procurement source data, so the pipeline must be able to classify them in order to exclude them. Modelling the value is what makes the exclusion checkable.

valuemeaning
companyAn incorporated supplier or bidder.
gov_bodyA government body.
natural_personAn individual. NEVER published — filtered from all released views.

PeriodTypeEnum

valuemeaning
