Using di.me

Why are some aspects of the Web-UI and the questionnaire not working in my Internet Explorer?

We try to make the Web-UI compatible with all browsers. However, there are some known issues with older versions of Internet Explorer (less v.10) that cannot be fixed within the research prototype. So, please use some other browser like Firefox or Chrome. Newer versions (10 and higher) of IE should also work if you deactivate the "compatibility mode".

After an action (sharing, uploading, registering a service, etc.) the UI is not showing the item as expected.

In these cases it helps to refresh the view (F5 in the browser). Normally this shouldn't be necessary, but in some cases there seems to be a problem with notifying the UI about changes.

Is this for mobile phones or desktops?

Both. You can currently use either the Android app (download http://dimetrials.bdigital.org:8080/dimemobile.apk ) or the Desktop client (URL at which you registered). The information stays synchronized between your mobile phone and desktop automatically.

Can I run my own server?

Definitely, yes! Please try out to set-up your own di.me server. In the wiki: Server-Installation-Guide you can find a description about which steps are required for this. However, at the moment some mid-level admin skills might be helpful to set up the system. But, please just try it out. If you have any questions or experience problems, please contact us. We'll be happy to help you with it.

What is the YellowMap-Service about? How can I register YM service?

The YellowMap service allows for showing nearby places according to your current position. When adding the service in "Settings", it is required to state an email address, password and your name. YellowMap service is a proprietary service provided by YellowMap.de. It is only available for the di.me servers run by the project consortium. If you are interested in using this service please contact YellowMap.

General questions about di.me functionality

What improvements does the di.me approach provide compared to other networks?

  1. Multiple identity management. di.me helps you to manage an overview of your digital identities, without necessitating that one identity is linked to another. For example, you could have two identities, "Bruce Wayne" and "Batman" - both of which have their own Facebook accounts, friends, etc. You can manage both of these identities with di.me. In di.me, these are called "profile cards" - a digital version of a business card that you get when you meet someone. So, if you share a picture to your one of your Friends using your "Batman" profile card, and later try to share the same picture to your "Friends"-group with your "Bruce Wayne" profile card, di.me will warn you about this: members of your "friends" group could start to associate your "Batman" and "Bruce Wayne" identities with the same person. But even if you aren't a superhero, most people still have two digital identities - a business identity with a positive image, and a friends identity with a more loose, party-like image. Maintaining those images separately and managing an overview of which contacts know which aspects of your image may be valuable for you via a tool like di.me.
  2. Trust management and recommendations. In di.me, you can tag each file and each contact with a privacy/trust index. This tells di.me how much 'confidentiality' or 'trust' a file or contact has. When you try to share confidential information to less-trusted contacts, di.me will warn you about this. If you consistently share confidential information to a particular less-trusted contact, di.me will ask you if you would like to raise the trust level for that contact, as you seem to trust them more. For example, you could mark a file called "Kathy Kane's Contact Info" with a high privacy level. When you share it to "Friends", which contains some people who have a low or medium trust level, di.me will warn you and ask if you are sure that you want to do this.
  3. Decentralization. In short, your data stays on your personal server - no third party can see the 'complete picture' of all your digital identities. So, security and data-backup issues can be handled on every server depending to the requirements of the user. In case you host your own server, you are in total control of your data, you also have the full responsibility about security, backups and availability. If you use a server provided by a service, you have to trust the service to handle your data according to your needs.

What happens when I connect to a service like LinkedIn or Facebook?

When you connect to a service, di.me will look up your contacts and map your network. During the mapping process, it looks up the personal attributes you have shared on each network (e.g. Employer, School, etc.), and compares your contacts and asks you whether similar contacts are the same person (e.g. "Paul Fisher" on Facebook and "Herbert Fisher" on LinkedIn), allowing you to teach di.me which digital identity your contacts know about you. No information is sent to any network unless you explicitly share it there. Also, no intelligent decisions are taken automatically: any action must be explicitly confirmed by the user. At the moment, we do not fully support sharing to other networks. This is however on the development roadmap. For example, if you choose to share a livepost to the "Twitter" group, a tweet with the text of that livepost will be shared to Twitter, but not to Facebook, LinkedIn, or any other connected service. No information is shared to any advertisers, other users, or any central server, either: your information is only stored on your personal server (which may be your own server or one of the provided servers from the consortium).
