Summary
Crimson Romance is the romance line at Adams Media. This is an ebook-first series. For this series, I helped with a transition to a CMS-based workflow. I was the sole developer on this series during my time at F+W Media, with 2 to 3 titles being published per week.
Description
Due to the quick turnaround with this series, I was presented with an interesting challenge. The CMS filled in the metadata fields for the EPUB export; however, since the content was outpacing the metadata for this fast-paced workflow, I had to enter in that information manually: the cover, author name, title, and ISBN. Initially, I set up a set of regexes that I would run upon opening the files, but eventually I created a Python script. The script is available here on github.
It’s also down here:

firstName = raw_input('Author\'s first name: ')
print(firstName)
lastName = raw_input('Author\'s last name: ')
print(lastName)

for file in os.listdir(bookFolder):
if file.endswith('.epub'):
foul = file
for file in os.listdir(bookFolder):
if file.endswith('.jpg'):
isbn = os.path.splitext(file)[0]
os.mkdir(isbn)
zip_ref = zipfile.ZipFile(foul, 'r')
zip_ref.extractall(isbn)
zip_ref.close()
epub_folder = os.path.join(bookFolder + '/' + isbn)
oebps_folder = os.path.join(epub_folder + '/OEBPS')
os.rename(isbn + '.jpg', 'cover.jpg')
