Current thinning of data in Slack

For information / messages sent via Slack, the same handling of public documents applies as in other activities at KTH.

Relevant control documents for handling public documents at KTH are available at The principle of public access to information  and Arkivering och diarieföring

It is the individual official / user who needs to make an assessment of whether the information is general or not. It is always the content that determines whether a document is public or not and as an employee at KTH, you have your own responsibility to handle and separate public documents correctly.

The Information Management Plan contains detailed management instructions as well as information on conservation requirements resp. thinning deadlines for public documents at KTH

All incoming and established (outgoing) information (= public document) is counted as a public document. Public documents may only be thinned out if there is support in the law.

Thinnable public documents include a. documents of minor and temporary significance that may be destroyed provided that the public's right of access is not violated and that the documents are deemed to be of no value to the administration of justice, administration and research.

Examples of such documents that may be thinned are

  • logs,
  • documents - received and prepared - of a general nature such as petitions, inquiries, and communications of a temporary and routine nature
  • documents received for information and which have not prompted any action

Examples of documents that are not public documents and may be cleared are

  • the content of the document is of a private nature
  • documents that are sent internally (eg internal communication between KTH employees via Slack) and do NOT belong to or add to a case expertise

Cleaning and thinning in Slack is proposed to take place automatically:

- for logs after 90 days at the earliest

- for messages internal and external (incoming, outgoing) are thinned after 90 days at the earliest

If a public document cannot be thinned within 30 days, it must be transferred to another medium for storage until the thinning period has expired or is preserved.

NOTE When requesting a public document, we are obliged to release these as long as the document is kept by the authority.

In the event of possible future integrations with other business systems, thinning / preservation of public documents must be investigated in the source system.

Naming rules for channels in Slack

If you use Slack to communicate with people, companies or projects that are outside KTH then you have to follow the channel naming rules for Slack. 

For Slack channels with external members the naming rules are

<school>-<department>-<external or ext>-<group or project or purpose>

Some examples in naming Slack channel


Try to use abbreviations for school and deparment when you are naming your channel.
You cannot use spaces in channel-names.

We reserve the right to rename or remove a channel that violates the naming rules.
