Section Overview

BORME organizes its daily publications into three distinct sections, each containing different types of mercantile registry information. Understanding these sections is essential for efficiently accessing the specific data you need.

Section A

Registered acts (Actos inscritos)

Section B

Other published acts

Section C

Public announcements

​
Section Structure

All sections fall under “SECCIÓN PRIMERA” (First Section) with different subsections: 
# From bormeparser/seccion.py:20-36
class SECCION:

See bormeparser/seccion.py:20-36 for the implementation.

Section A Organization

Section A is organized by province, with separate PDF files for each province: 
BORME-A-2016-101-28.pdf (Madrid)
BORME-A-2016-101-29.pdf (Málaga)
BORME-A-2016-101-08.pdf (Barcelona)
...
Each provincial file contains all registered acts for companies in that province’s mercantile registry.
Province codes are 2-digit numbers. For example: 28 = Madrid, 29 = Málaga, 08 = Barcelona. See bormeparser/provincia.py for the complete list.

​
Data Structure in Section A

Each company announcement (anuncio) in Section A contains:
  1. Company identification
    • Company name (empresa)
    • Registry office (registro)
    • Announcement number (id)
  2. Acts (actos)
    • One or more registered acts
    • Each act has a type and associated data
  3. Registry data (datos registrales)
    • Official registry information
    • Registration numbers and dates
# Example from bormeparser/borme.py:142-156
class BormeAnuncio(object):
    def __init__(self, id, empresa, actos, extra, datos_registrales=None):
        self.id = id
        self.empresa = empresa
        self.registro = extra["registro"]
        self.sucursal = extra["sucursal"]
        self.liquidacion = extra["liquidacion"]
        self.datos_registrales = datos_registrales or ""

​
Section B: Otros Actos

Official Name: “SECCIÓN PRIMERA - Otros actos publicados en el Registro Mercantil” Section B contains other acts published in the Mercantile Register that don’t fall under the main registered acts category.

​
What Section B Contains

Section B typically includes:
  • Registry closures: Provisional closures of registry entries
    • Cierre provisional por baja en el índice de Entidades Jurídicas
    • Cierre provisional por revocación del NIF
    • Cierre provisional por Impuesto de Sociedades
  • Registry reopenings: Reapertura hoja registral
  • Reactivations: Reactivación de la sociedad
  • Administrative acts: Various administrative registry actions
  • First registrations: Primera inscripción
  • Preventive annotations:
    • Anotación preventiva por demanda de impugnación
    • Anotación preventiva por declaración de deudor fallido
Section B acts are generally administrative or procedural in nature, as opposed to the substantive business acts in Section A.

​
Section B Organization

Like Section A, Section B is also organized by province: 
BORME-B-2016-101-28.pdf (Madrid)
BORME-B-2016-101-29.pdf (Málaga)
...
Not all provinces may have Section B publications on a given day. Section B is published only when there are relevant acts to report.

​
Section C: Anuncios

Official Name: “Otros anuncios” (Other announcements) Section C contains public announcements that companies are required to publish, such as shareholder meeting notices and corporate decisions.

​
What Section C Contains

Shareholder Meetings

Convocatorias de juntas - Notices of annual general meetings and extraordinary meetings

Capital Changes

Public notices of capital increases and reductions requiring shareholder approval

Financial Announcements

Annual accounts, balance sheets, and financial statements

Other Public Notices

Various announcements companies must legally publish

​
Section C Organization

Unlike Sections A and B, Section C is NOT organized by province. Instead, it’s organized by announcement type (emisor): 
# Example structure from bormeparser/download.py:220-233
{
    'CONVOCATORIAS DE JUNTAS': {
        'AUTOBUSES INTERURBANOS, S.A.': 'https://...',
        'BANCOFAR, S.A.': 'https://...'
    },
    'AUMENTO DE CAPITAL': {
        'BRANDCONT SERVER, S.L.': 'https://...'
    },
    'REDUCCIÓN DE CAPITAL': {
        'ABENGOA, S.A.': 'https://...'
    }
}

​
Section C File Format

Section C files use a different naming convention: 
BORME-C-{YEAR}-{ANNOUNCEMENT_NUMBER}.{pdf|xml|htm}

Example: BORME-C-2016-2310.pdf
Each announcement number corresponds to a single company announcement.
Section C is available in PDF, XML, and HTML formats. The HTML format can be easier to parse for Section C data.

​
Accessing Section C

from bormeparser import BormeXML
import datetime

date = datetime.date(2016, 4, 20)
bxml = BormeXML.from_date(date)

# Get Section C URLs (PDF format)
urls_pdf = bxml.get_url_seccion_c(date, format='pdf')

# Get Section C URLs (HTML format)
urls_html = bxml.get_url_seccion_c(date, format='html')

# Get Section C URLs (XML format)
urls_xml = bxml.get_url_seccion_c(date, format='xml')
See bormeparser/download.py:220-266 for the Section C implementation.

​
SECCION Enum Usage

The bormeparser library provides a SECCION class for type-safe section references: 
from bormeparser.seccion import SECCION

# Use the enum constants
print(SECCION.A)  # 'A'
print(SECCION.B)  # 'B'
print(SECCION.C)  # 'C'

# Convert from BORME text
seccion = SECCION.from_borme(
    seccion='SECCIÓN PRIMERA',
    subseccion='Actos inscritos'
)
print(seccion)  # 'A'
See bormeparser/seccion.py:26-36 for the from_borme() method.

​
Choosing the Right Section

1

For company incorporations, dissolutions, and officer changes

Use Section A - it contains all the primary registered acts.
2

For registry administrative actions

Use Section B - it contains closures, reopenings, and administrative acts.
3

For shareholder meeting notices and public announcements

Use Section C - it contains legally required public announcements.
4

For comprehensive coverage

Parse all sections - many use cases require monitoring all three sections.

Working with Sections

​
Downloading by Section

from bormeparser import download_pdfs
from bormeparser.provincia import PROVINCIA
from bormeparser.seccion import SECCION
import datetime

date = datetime.date(2016, 6, 1)
path = "./bormes"

# Download all Section A provinces
download_pdfs(date, path, seccion=SECCION.A)

# Download Section A for specific province
download_pdfs(date, path, seccion=SECCION.A, provincia=PROVINCIA.MADRID)

# Download all sections for specific province
download_pdfs(date, path, provincia=PROVINCIA.MADRID)

​
Parsing Different Sections

from bormeparser import parse
from bormeparser.seccion import SECCION

# Parse Section A
borme_a = parse("BORME-A-2016-101-29.pdf", SECCION.A)
for anuncio in borme_a.get_anuncios():
    print(f"Company: {anuncio.empresa}")
    for act in anuncio.get_actos():
        print(f"  {act[0]}: {act[1]}")

# Parse Section B (same API)
borme_b = parse("BORME-B-2016-101-29.pdf", SECCION.B)
Section C requires different parsing logic due to its different structure. The library provides specialized parsers in bormeparser/backends/seccion_c/.
