Modifying Date

This post-conversion indexing pipeline extension (IPE) script sample modifies the item date.

Post-conversion Extension Script Sample:

from dateutil.parser import parse
from dateutil.relativedelta import relativedelta
from datetime import datetime, date
import re

def get_flattened_meta():
    flattened = dict()
    for m in document.get_meta_data():

            flattened[metadata_name.lower()] = metadata_values
    normalized = dict()
    for metadata_name, metadata_values in flattened.items():
        if len(metadata_values) == 1:
            normalized[metadata_name] = metadata_values[0]
        elif len(metadata_values) > 1:
            normalized[metadata_name] = ';'.join([str(value) for value in metadata_values])
    return normalized

# When the metadata is wrong and you don't have any date, it puts it one year before
document.add_meta_data({'Date':str(parse_date_with_trigger(meta_data['modificationdate'], \
