1	# obsidian-bases: Obsidian's Database Layer
2
3	Obsidian Bases (launched 2025) turns vault notes into queryable, dynamic views. Tables, cards, lists, maps. Defined in `.base` files. No plugin required; it is a core Obsidian feature.
4
5	Substrate preference (v1.7+): This skill is a self-contained fallback. Prefer `kepano/obsidian-skills` as the authoritative substrate — its `obsidian-bases` skill is the canonical reference for Bases YAML, formulas, and view definitions. If you see an `obsidian-bases` skill available without the `claude-obsidian:` namespace, that is kepano's version: use it. The reference below is provided so the plugin remains functional when kepano's marketplace is not installed. Install: `claude plugin marketplace add kepano/obsidian-skills`.

9	## File Format
10
11	`.base` files contain valid YAML. The root keys are `filters`, `formulas`, `properties`, `summaries`, and `views`.
12
13	```yaml
14	# Global filters: apply to ALL views
15	filters:
16	and:
17	- file.hasTag("wiki")
18	- 'status != "archived"'
19
20	# Computed properties
21	formulas:
22	age_days: '(now() - file.ctime).days.round(0)'
23	status_icon: 'if(status == "mature", "✅", "🔄")'
24
25	# Display name overrides for properties panel
26	properties:
27	status:
28	displayName: "Status"
29	formula.age_days:
30	displayName: "Age (days)"
31
32	# One or more views
33	views:
34	- type: table
35	name: "All Pages"
36	order:
37	- file.name
38	- type
39	- status
40	- updated
41	- formula.age_days
42	```
43
44	---
45
46	## Filters
47
48	Filters select which notes appear. Applied globally or per-view.
49
50	```yaml
51	# Single string filter
52	filters: 'status == "current"'
53
54	# AND: all must be true
55	filters:
56	and:
57	- 'status != "archived"'
58	- file.hasTag("wiki")
59
60	# OR: any can be true
61	filters:
62	or:
63	- file.hasTag("concept")
64	- file.hasTag("entity")
65
66	# NOT: exclude matches
67	filters:
68	not:
69	- file.inFolder("wiki/meta")
70
71	# Nested
72	filters:
73	and:
74	- file.inFolder("wiki/")
75	- or:
76	- 'type == "concept"'
77	- 'type == "entity"'
78	```
79
80	### Filter operators
81
82	`==` `!=` `>` `<` `>=` `<=`
83
84	### Useful filter functions
85
86	\| Function \| Example \|
87	\|----------\|---------\|
88	\| `file.hasTag("x")` \| Notes with tag `x` \|
89	\| `file.inFolder("path/")` \| Notes in folder \|
90	\| `file.hasLink("Note")` \| Notes linking to Note \|
91
92	---
93
94	## Properties
95
96	Three types:
97	- Note properties: from frontmatter: `status`, `type`, `updated`
98	- File properties: metadata: `file.name`, `file.mtime`, `file.size`, `file.ctime`, `file.tags`, `file.folder`
99	- Formula properties: computed: `formula.age_days`
100
101	---
102
103	## Formulas
104
105	Defined in `formulas:`. Referenced as `formula.name` in `order:` and `properties:`.
106
107	```yaml
108	formulas:
109	# Days since created
110	age_days: '(now() - file.ctime).days.round(0)'
111
112	# Days until a date property
113	days_until: 'if(due_date, (date(due_date) - today()).days, "")'
114
115	# Conditional label
116	status_icon: 'if(status == "mature", "✅", if(status == "developing", "🔄", "🌱"))'
117
118	# Word count estimate
119	word_est: '(file.size / 5).round(0)'
120	```
121
122	Key rule: Subtracting two dates returns a `Duration`. Not a number. Always access `.days` first:
123	```yaml
124	# CORRECT
125	age: '(now() - file.ctime).days'
126
127	# WRONG: crashes
128	age: '(now() - file.ctime).round(0)'
129	```
130
131	Always guard nullable properties with `if()`:
132	```yaml
133	# CORRECT
134	days_left: 'if(due_date, (date(due_date) - today()).days, "")'
135	```
136
137	---
138
139	## View Types
140
141	### Table
142	```yaml
143	views:
144	- type: table
145	name: "Wiki Index"
146	limit: 100
147	order:
148	- file.name
149	- type
150	- status
151	- updated
152	groupBy:
153	property: type
154	direction: ASC
155	```
156
157	### Cards
158	```yaml
159	views:
160	- type: cards
161	name: "Gallery"
162	order:
163	- file.name
164	- tags
165	- status

173	order:
174	- file.name
175	- status
176	```
177
178	---

180	## Wiki Vault Templates
181
182	### Wiki content dashboard (all non-meta pages)
183
184	```yaml
