==Project Exchange Format==

In March 2019, the [[Rotterdam Exchange Format Initiative]] (REFI) launched a new open exchange standard for qualitative data called QDA-XML.,<ref>{{citeCite journal |last=Evers |first=Jeanine |date=May 2020 web|title=LaunchWhat –is Codebookthe REFI-QDA Standard: Experimenting With the Transfer of Analyzed Research Projects Between QDA Software Exchange|url=https://www.qdasoftwarequalitative-research.orgnet/launch-the-codebook-exchangeindex.php/fqs/article/download/3439/4598?inline=1 |accessdatejournal=19Forum: MarchQualitative 2019Social Research |volume=21 |issue=2 |pages=22}}</ref> however, the Computer Assisted Qualitative Data Analysis (CAQDAS) Network Project had been formally established in 1994.<ref name=":0" /> The aim is to allow users to bring coded qualitative data from one software package to another. Initially supportSupport was includedinitially inadopted by [[Atlas.ti]], [[QDA Miner]], [[Quirkos]] and [[Transana]], and ishas nowsince been implemented ininto [[Dedoose]], [[MAXQDA]] and, [[NVivo]] asand wellmore.<ref>{{citeCite web |title=ProductsChoosing –a ProjectCAQDAS package {{!}} University of Surrey Exchange|url=https://www.qdasoftwaresurrey.orgac.uk/productscomputer-projectassisted-exchangequalitative-data-analysis/resources/choosing-appropriate-caqdas-package |accessdateaccess-date=2023-10-19 March 2019|website=www.surrey.ac.uk}}</ref> Although this was not the first standard to be proposed, it was the first to be implemented by more than one software package, and came as the result of a collaboration between vendors and community representatives from the research community. Previously there was very little capability to bring data in from other software packages.

==Training==

The CAQDAS Network Project hosts events on the use of CAQDAS packages for qualitative and mixed-methods analysis. They include:<ref name=":0" />

* fee-based in-person short courses

* open-registration Webinars designed to raise awareness

* open-registration Webinars that are methodological or pedagogical in nature

* podcasts
