Because of the open source basis liatos can easily be adapted and extended due to specific requirements.

To make all tools comparable for you, we have created a set of categories where every tool has its own description, whether it fullfills the categories or not. You can read a detailed description of each category on this page.

Enterprise Communication

liatos is especially designed to support transparent communication. Because of it's very intuitive user role system, everyone in a particular workspace can easily participate in or can initiate enterprise discussions. litatos provides forum functionality in every work- or subspace. Every kind of content (except discussions) can be commented by users. Every work- or subspace can be configured to provide only the needed functionalities. For more official spaces the access can be opend for everyone or for "guests" who are not able to edit content. Moderators can configure workspaces and have access rights to change or delete content if necessary. liatos does not provide rating functionality. Blog functionality is currently under development.

Collaboration and Knowledge Exchange

liatos enables users to collaborate on and across all levels of an organization by providing workspaces and functionality with an easy and intuitive role system. The access to workspaces can be restricted on the level of individual users, by a general code, or it can be opend for everyone. Knowledge exchange is supported by providing discussions, materials (text creation), appointments, tasks, profile pages. Users can upload files to any kind of entry. They can structure the content with tag clouds, categories als well as by cross-linking any content within a workspace. Materials have version control and wiki export functionality. Appointments and tasks have export and subscription functionality. Workspaces can be configured to their functionality scope. Access control can easily be handled by protecting sensitive information in particular workspaces. liatos does not provide pdf- or word export,office integration bookmark-sharing tools, microblogs or a desktop connector.

Social Networking and Expert Search

liatos is not a social network as defined here. It focuses on team collaboration rather than on expert search or status following. However, liatos provides a profile page for every user where she or he can upload a photo, present contact information and give a free text description for skills, expertise or interest. liatos does also explicitly not provide access to a user's activity on the platform due to avoid activity control or group pressure. Our long-term scientific evaluation shows that such control can easily lead to activities that does not represent their work with the content.

Personal Information Management

liatos provides a personal space where users can collect content from any workspace she or he has access to. Users are able to give the content an individual structure by using tags, categories and cross-link functionality. Persoanl spaces are only accessible by the particular user. In addition, this space provides possibilities to integrate RSS feeds, twitter feeds, activitiy feeds from liatos workspaces and more. In addition, it provides advanced search options across workspaces and content types. This personal space is currently under development and will be available in autumn 2010.

Project Management

liatos provides support for lightweight and communication-oriented project management. It's high usability allows project members to easily document project progress in a workspace. Announcement functionality can be used to give central information to all project members. The tasks functionality enables users to document task status, responsibility, estimated time budget and steps to document progress (time tracking). The tasks list gives an overview over current and finished tasks. Tasks can also be cross-linked to entries in the project calendar. Project results can be exported to a wiki page or in other workspaces. liatos explicitly does not provide folder-based file management. Instead, it supports users by structuring their content in a more flexible and topic related way with cross-links, categories and tag clouds.

Operational Flexibility

liatos is availabe either as a software, as a service solution or as an on-premise solution that can be installed on any server and that can be adjusted to a company's specific infrastructure and requirements. It works best on a linux system with an apache web server and a mySQL data base. It's user management can be coupled to a company's own system like LDAP or AD. It follows standards of data exchange and web representation. Basing on open source components, it is possible to extend features due to specific requirements. It is highly scalable and proven in large organizations with about 30.000 users. liatos is available in German and English.

Customization & Extensibility

Every workspace can be configured to select only needed functionality. In addition, some extensions and plug-ins can be restricted or provided portal-wide. The look-and-feel of workspaces can also be adjusted by selecting colours, a background image and a logo. The portal of the system can also be adjusted to a corporate design. liatos explicitly does not provide configuration on a personal level to to ensure best-possible usability. The design philosphy of ensuring that all users see the content in the same way proved to enhance usability. One exception is the personal space which allows personalization with widgets. liatos is professionally provided by the effective WEBWORK GmbH and it profits from an active developer community around the open source components like CommSy or PmWiki.

Data & Security

liatos has a very easy and intuitive rights management. Every member of a workspace has the same rights and has access to everything the others have. Exceptions are: users can determine wether an entry is editable by others or not; moderators of a workspace can edit everything and are able to configure the workspace. This role model ensures that access rights are very transparent to all users. liatos uses TLS/SSL encoding. The SaaS solution runs on redundant hardware, is protected by firewalls, has a direct connection to 110 GBit backbone. The data processing centre has security services, physical access control and fire control. In additon liatos provides security by 24x7-monitoring of the servers, virus scanning, regular backups, no Java applets or ActiveX components and by following privacy laws. SSO and LDAP are supported.

    Vielleicht mags es auch mal jemand auf "deutsch" lesen: Liatos ist eine hervorragende WEB-Kooperations-Plattform auch im komerziellen Umfeld. Insbesondere KmU'S (Klein- und mittelständige Unternehmen) und Netzwerke können preisgünstig, schnell, unbürokratisch und sehr effektiv einsteigen und ohne großen Aufwand (keine Server, kein konfigurieren usw.) sofort starten. Es ist intuitiv erlernbar und nur der Moderator sollte sich ein wenig mehr einarbeiten, um alle Möglichkeiten zu erkennen und ggf. einzusetzen. Wir haben es in unserem und mehreren anderen Netzwerken sehr erfolgreich eingesetzt und die Akzeptanz ist von Beginn an hoch !

    Good platform, nearly very good! I was working for several years with the CommSy based collaborative platform at the University of Hamburg (which is technically nearly the same as LIATOS). I like the straightforward and non hierarchical way of doing things with the platform. Currently I'm using a light version of LIATOS to collaborate with some customers of my business. Five stars for the platform if you run it as a serice. Only disadvantages: difficult to theme the platform, and for me it's too hard to get the basic (open source) software running on my own server. All in all four and a half stars!

    I use Liatos in every consulting project in which people should cooperate with each other in the short term and in an uncomplicated way. The main advantage: Liatos exceeds organizational boundaries, and IT boundaries, it is immediately available and you have to learn almost nothing to start working with the tool.

    As a collaboration plattform liatos provides very high usability and is suitable for a wide variety of working groups. Contrary to most software solutions in this area liatos offers an intuitive user experience. It adresses ICT-novices as well as technological champions. Thus, it is especially recommendable for those virtual teams oder networks where ICT is a means to an end to facilitate communication and work flows. All thumbs up!
