What happens to the platform after the funding runs out?

The ConfIDent project ends in December 2022. TIB has committed itself to maintain the platform for at least 3 years after the of the project. The ConfIDent team already has handed in a proposal for a follow up project to continue the development of the service for another 3 years.

Why not use the GND (Gemeinsame Normdatei) instead of ConfIDent?

The GND already has an impressive collection of conference and event related metadata which is constantly growing (*&filter=%2B%28type%3AConferenceOrEvent%29). So why is there a need for a new project that "redoes" a lot of what is already accomplished with the GND? There are several reasons for why the GND and ConfIDent are not the same and serve different needs:

  • ConfIDent purely focuses on academic events and series. Conferences and events in GND also contain a lot of cultural events like festivals or art exibitions (e.g.
  • The GND metadata schema already contains a lot of valuable information but is still fairly limited and can't be adjusted as flexible as we can adjust the ConfIDent metadata schema.
  • ConfIDent includes smaller academic events like workshops which do not necessarily provide output such as proceedings. GND entries are usually only created when a new ressource is catalogued by a librarian and for example a conference is referenced in a proceedings.
  • ConfIDent wants to enable any interested user to enter events and event series themselves. It is supposed to be a community driven and crowd sourced endeavour.
  • ConfIDent is committed to provide a platform that enables the user to browse events and to find the most relevant ones.
  • In the future, ConfIDent will enable automated data imports from trusted souces. GND will be one of those.

Although ConfIDent and GND have different purposes there is value in creating a connection between the too. In the future users of the GND data will find links to the DOI of the representation in ConfIDent. Here is a first showcase: The DOI 10.25798/6g5z-xw83 is marked in the MARC XML representation of the GND metadata in field 024a. Conversely the ConfIDent metadata will contain GND IDs.

Metadata related questions

How do I get my event listed in ConfIDent and how do I get a DOI for my event?

If you are interested in having your event indexed in ConfIDent send us a informal inquiry at confiden[@] We index all academic events that are not "predatory" (we try not to index predatory conferences) and can be considered "academic". This explicitely also includes smaller events like workshops - not only large conferences. In the future you will be able to enter and edit events yourself. Every entry will receive a DOI.

Which metadata fields are going to be implemented?

To get an overview about the metadata fields that we plan on implementing you can check out the ConfIDent Metadata Schema. There you will find detailed desciptions of the planned metadata fields for events and event series. The Metadata Schema represents the blue print for the continuos development of the ConfIDent platform. As the platform it will be contiuosly improved and extended. We track the conception of new fields in github. Your feedback is very welcomed. Feel free to make new suggestions for fields.

How are events and event series classified in terms of their academic fields?

Events and event series must be classified with terms that researchers are familiar with and with which they can identify themselves and their scientific community. The smaller and more specialised a field is, the less likely it is that these terms will be found in a general classification system. However, in order to organise large amounts of scientific resources, such classification systems with standardised vocabularies are necessary. The use of standardised vocabularies also enables interoperability, i.e. integration with metadata from other information sources. ConfIDent therefore uses a hybrid approach: a group of curators - usually members of the scientific communities - can enter new keywords that may or may not match terms of a classification system. These are then matched by librarians to the terms of different classification systems. We use the OECD's Fields of Science (FOS) classification for this. The use of other vocabularies is being investigated.

The visualisation of academic fields and the possibility to browse by field will be improved upon in the future. Currently we offer a list of all used terms. But with this query you can for example already see all terms and thus events mapped to the OECD FOS classification "Computer And Information Sciences".

Will ConfIDent make use of PIDs?

Yes! Actually we already assign DOIs to some of our events and event series e.g. or As you can see, ConfIDent provides landingpages for those DOIs. In the future you will be able to find all the metadata related to the DOI and more on the respective ConfIDent landingpage. We were able to reuse the DataCite schema mostly without "bending" it too much. We gave an explanation how we are using the schema in this blog article.

How can I reuse ConfIDent's metadata?

Semantic Media Wiki comes with the option to construct customized "ask-queries" (see SMW's documentation). You can make use of this function by navigating to either the Event Series page or the Events page and clicking "Show All Events/ Event Series". This query for example lists all events that have received a DOI so far.

You will then find a table produced by the default query. You can coustomize the query by clicking on the pen.

The page will extend to the top (scroll up) where you can set conditions for your query and adjust the output.

You can download the output of your query by clicking on one of the different dataformats available.

How do you we deal with the issue of predatory conferences?

We aim to include no or as few predatory conferences as possible in our platform. How we try to do that is described in detail in our Predatory Identification workflow.

Request an account

Experience has shown that unmoderated platforms tend to be flooded with questionable conferences. For this reason, account requests must be approved. Follow the instructions and request your ConfIDent account.

How to enter events and event series?

Once you have your ConfIDent account, you can enter events and event series yourself. Your edits will be reviewed before approval.

How to use the API

ConfIDent is based on MediaWiki, whose API can be used for querying and editing content. Unfortunately, MediaWiki's API is not yet based on REST, which means that the interface is typically used by so-called "bots" instead of common REST tools.

In order to retrieve content from ConfIDent or to create or edit content, it is necessary to know its structure. The most important structures (classes) are "Event Serie", "Event" and "Academic Field". Each entry in ConfIDent that belongs to one of these classes is stored in its own namespace and assigned a unique ID.

For example the Event Series AGILE-GI - AGILE conference on Geographic Information Science is stored unter Event_Series:D4685b15-8c8f-4271-a527-6abca54205ec.

Users usually use forms to create content. These forms create the corresponding pages in the associated namespace and automatically assign the UUIDs for the page title. The values entered in the form are saved in templates on the pages.

The values of the form fields are transferred to the template parameters. ConfIDent then automatically creates semantic annotations within the templates. The templates are very important for API users, as these are the easiest way to determine the possible parameters for API queries. To view a wiki page in the source code and also view the keys and values of the template, select "Edit source" from the "Tools" menu or add "?action=edit" to the URL.

An extract from the above example look like:

{{Event Series
|Title=AGILE conference on Geographic Information Science
|Recurrence Period=1
|Recurrence Unit=year
|Academic Field=Cartography; Citizen Science; Digital Earth; Earth Observation Systems; GI Education and Training; GIScience; Geo-AI; Geodesign; Geographic Information Systems; Geoinformatics; Geoinformation Science and Technology; Geonensor Networks; Geostatistics; Navigation; Sensor Web; Smart City; Spatial Data; Spatial Data Infrastructures; Spatial Databases; Spatial Statistics; Volunteered Geographic Information
|Official Website=

To see the resulting semantic annotations of such a page, select "Browser properties" form the "Tools" menu on the page footer.

The easiest way to make queries is via the "ask" API module.

Note the namespace prefixes that might be required, like for "Academic Field". These namespace prefixes are not usually part of the parameter of a template, but are only added one level later during semantic annotation.

Example: Query Events Series with Academic Field "Digital Earth":[[Category:Event%20Series]][[Academic%20Field::Academic%20Field:Digital%20Earth]]
    "query": {
