Dataset codebook

The EUPLEX dataset consists of EU legislative procedures. The variables therefore relate to the procedure. Procedures have a number of variables relating directly to them, such as their reference number or their name. Within a procedure, various events, such as the adoption of a proposal or a vote, can occur. These events may have documents attached to them, e.g. the 'adoption of proposal by Commission' event may contain the actual proposal document. Variable naming rules are used to differentiate between event- and document-related variables.

Data structure

Events

All event-related variables use the prefix e_. All events have a legal date assigned to them, that is stored in the e_legal_date variable.

Currently only the following events are included in the dataset:

  • proposal: adoption of proposal by submitting institution, usually the Commission (ADP_byCOM), start of the legislative procedure

Documents

Documents are always attached to an event. All document-related variables carry the doc_ prefix. In theory, an event can also contain multiple documents. Currently, only the proposal text of the proposal event is included in the dataset.

Variables

Variable Name Type Description
Procedure ID procedure_id String Procedure ID as used in EUR-Lex urls
Procedure reference procedure_reference String Complete procedure reference
Procedure notice CELLAR uri uri__cellar String CELLAR uri of the procedure notice
Legislative procedure type procedure_type String Type of legisaltive procedure used
Proposal adopted proposal_adopted Logical Was the proposal adopted? (information based on 'DOSSIER_ADOPTED-PROPOSAL' tag in procedure notice)
Proposal pending proposal_pending Logical Is the proposal still pending? (information based on 'DOSSIER_PENDING-PROPOSAL' tag in procedure notice)
EUROVOC domain(s) eurovoc_... Logical Set of logical indicators marking whether a procedure is tagged with a EUROVOC identifier belonging to the specific EUROVOC domain
Procedure title title String Title of the procedure
Events
Event Name/ID event String Event identifier using 'nice' names. Currently only contains 'proposal' (corresponds to 'ADP_byCOM' events in procedure notice)
Legal Date e_legal_date String (Date) The date of an event as registered in EUR-Lex
Event-document CELEX uris e_doc_celexs String The CELEX uri(s) of the main document attached to an event (used to merging documents to events)
Multiple main documents e_multi_main_docs Logical Does the event have multiple main documents? if TRUE, the CELEX uri without a bracket or 'R' postfix is preferred for matching
Responsible institution corporate body e_resp_inst__corp_body String The 'corporate body' name of the responsible institution for a specific event. For proposal, this is usually the abbrevation for the responsible Commission DG.
Documents
Document Name/ID doc String Document identifier using 'nice' names usually corresponding to an event name. Currently only contains 'proposal' (corresponds to 'ADP_byCOM' events in procedure notice)
Document CELEX uri doc_uri_celex String The CELEX uri of the document (used for matching events to documents)

Instrument subtype doc_leg_instr_subtype String The subtype of legislative insturment of the text (Legislation, Recast, Codification) taken from the title of a text
Implementing act doc_leg_instr_implementing Logical Is the text an implementing act? Taken from the 'RESOURCE-TYPE' identifier of a document notice
Amending act doc_amending Logical Is the text an amending act? Based on document title (see online appendix for additional information)
'and' amending act doc_and_amending Logical Is the text an 'and' amending act? Based on document title (see online appendix for additional information)
Adapting act doc_adatping Logical Is the text an adapting act? Based on document title
Repealing act doc_repealing Logical Is the text a repealing act? Based on document title
'and' repealing act doc_and_repealing Logical Is the text a 'and' repealing act? Based on document title
Document title doc_title String Title of the text
