XML-RPC

Hi. I am wondering if you can tell me if it is possible to use XML-RPC to post into the EG-Series areas of the WP DB?

For example, I have the following code which works fine but I need to possibly add a similar post syntax for EG-Series:

post_info = {
‘title’: title,
‘description’: content,
‘dateCreated’: date_created,
‘categories’: categories,
‘mt_keywords’: tags,
‘wp_author_id’: self.author_id[record[‘Author’]],
‘wp_author_display_name’: record[‘Author’],
}

Is this possible?
