As John said, I believe you can fulfill this use case with Jive today:
- An attorney who publishes his/her legal reserved drafts of documents to his/her secure web site area --> post the document to a private place in the community (group, space, or personal container)
- Some of the attorney's clients are able to access their own "accounts" on the attorney's web site to follow their cases and revise the published drafts --> allow self-registration in the community or add the clients, then invite these users to the private places set up for their accounts, or share private content with them.
- Around each document a dedicated discussion should be opened (created) to let clients and attorney "talk" about the related document --> threaded comments on documents make this easy, as well as option for new discussions in the private place.
- The client may subscribe to receive feeds regarding his/her comments --> they'll get email notifications by default on content they've participated in, and can choose to get notifications on everything they follow or in places they choose.
- The attorney receives email notification on a per-post basis and a daily digest of what's going on regarding all discussions concerned --> same default as above, plus can choose frequency of the digest from the UI.
- The attorney should be able to use API which link all discussions regarding different documents to his/her desktop or web application that manage relative matter --> we do have published APIs for accessing content, as well as deep integrations with Outlook and Office.
- The attorney is able to give immediate answers from his/her smartphone, website or desktop application --> and tablet too!
- A discussion should permit participants to post attached files, images and URLs
- The discussion records should be absolutely private and never shared on the web. Hence, no Twitter, Facebook nor Google Plus should appear anywhere in the discussion context
- A discussion may be closed and downloaded in a PDF file, for instance to be archived locally or used according to both parties needs --> Discussions can be locked. You can print any content or view as a PDF. The only caveat is that View as PDF on documents does not include comments, so you'll need to use print to PDF for that option.
We are also working on a new feature for Jive 6 that you may find helpful for this use case, as it effectively segregates each client for complete confidentiality so that no one outside a given attorney-client relationship can see, for example, that a particular user is registered in the community. It will work similarly to what's described above, except that clients would only have access to the social groups they're invited to, and not to any global content (browse all people, content, status updates, etc.). You're welcome to join the conversation around this work in Engage Partners.
Hope this helps!
