Building a Jobware dataset beyond single ads
Coverage on Jobware starts from its own directories. Category pages exist per Berufsfeld, per city and per Anstellungsart - Teilzeit, Werkstudenten, Freelancer, Minijobs, Quereinsteiger, Befristung - and combine into addresses such as IT jobs in Berlin. Search sorts by relevance or date and narrows by working time, ad type and four experience level bands: Einsteiger, Professional, Senior and Lead. Paging runs out before the largest categories do, so we slice by field, city and band and merge on the job id.
The Inserentenverzeichnis is an advertiser directory of every company with live ads, A to Z, each linked to its ad list. The Unternehmensprofile, Jobware's company profiles, add a self-description, a benefits list from Gleitzeitregelung to Mobilitätsbudget, and awards. Together they make an employer table that joins to the ads.
Repeated runs turn cards into a history: when an ad appeared, how long it stayed, when it came back, how an employer's volume moves by month. Ads Jobware takes in from other sources show their card to anyone but ask for a sign-in before the full text; when that text matters, a project can run on an account registered through Jobware's own sign-up form.
