How To Use Obsidian: Properties, DataView, & ONE HUGE PROBLEM TO AVOID

Obsidian’s new Properties workflow lets users build structured “metadata” for notes without hand-writing YAML front matter, and that metadata can then power DataView dashboards that filter and aggregate information across a vault. The practical payoff is straightforward: instead of relying only on folders, links, or hashtags scattered through notes, users can store consistent fields—like director, release year, genre, and tags—at the top of each note and then generate dynamic lists or tables from that structured data.

The walkthrough starts with a movie-tracking example. Each movie note stores details such as director (e.g., “Wachowskis”), release date (e.g., “1999”), genre (e.g., “action sci-fi”), and tags (e.g., “action,” “kung fu,” “martial arts,” “explosions”). Previously, doing this well often meant creating templates and/or writing front matter manually, which requires correct YAML syntax (including the “three dashes” structure) and is easy to break with small punctuation mistakes. The update shifts that burden: enabling the core plugin “Properties View” surfaces a sidebar UI where users can add fields and choose property types—text, list, number, checkbox, or date/time—so the metadata stays organized and collapsible right at the top of the note.

A key detail is that property types act like guardrails. If a field is defined as a number, DataView and other tooling can treat it as numeric; if it’s text or a list, it behaves accordingly. That reduces the risk of entering incompatible data (like words into a field meant for graphing numbers), which matters when later queries depend on consistent typing.

Once metadata lives in Properties, DataView becomes the next step: it can query notes by folder and property values to produce filtered views. The example uses a DataView list query that pulls results from the “movies” folder where a tag equals “action,” returning only matching notes (initially “The Matrix”). The walkthrough then adds more complex filtering using logical conditions (e.g., requiring both “action” and “classic” tags) so users can build “grouped” pages like “Action Films” or “Classic Movies” that stay automatically updated as new notes are added.

The most important warning comes later: DataView queries can fail in confusing ways if property names or values include spaces in the wrong place. A specific troubleshooting moment shows a “parsing failed” error when trying to query a field named “release date.” Removing the space (using “releasedate” instead) fixes the table output. The presenter notes that this can force hours of cleanup across an entire vault if spaces were already used inconsistently. The takeaway is blunt: when defining property keys for DataView, avoid spaces—use underscores, dashes, or capitalization instead—so future dashboards don’t break.
