- alternativni pristup k filesystemu
2020-11-05 11:00:58 +01:00
- file storage jakozto database; database jakozto file storage
- fs ⇋ db ⟹ allmighty library

# Summary
#czech
> v podstate moje idea je :
## Base structure
> - databaze kde mas dva druhy objektu: data, a meta
2020-11-05 11:16:22 +01:00
> - (jedinej rozdil je, ze data actually odkazujou [[hash]]em na nejakej file, a meta neodkazujou nikam, jenom slouzej jako "anchor")
2020-10-30 10:22:55 +01:00
> - a ke kazdymu objektu muzes mit arbitrarni keys a values
2020-11-05 11:16:22 +01:00
> - kazdy takovy key/value tvori jeden `E/A/V` triplet (see [Entity Attribute Value model (Wikipedia)](https://en.wikipedia.org/wiki/Entity%E2%80%93attribute%E2%80%93value_model)):
2020-11-05 11:06:07 +01:00
> - `E`ntity = objekt (`neconeco.mp3`, resp. jeho [[hash]])
> - `A`ttribute = klic (`year`)
> - `V`alue = hodnota klice (`2020`)
> - struktura filesystemu samotna je taky `E/A/V` triplet: `FILE_shaiusdhuijhngsoyuhsdf BELONGS_TO_DIRECTORY shaoidsuhjaoijoiasjdioj`
> - (kazdej `E/A/V` je taky objekt na kterej se da odkazovat, kdyby sis chtel anotovat anotace)
2020-10-30 10:22:55 +01:00
## Schemas
> - objekty maj kategorie, ktery znamenaj ze se muzes spolehnout ze objekt co je otagovanej "radio" ma: cas pridani, slozku, heaviness, etc.; co je otagovanej "public" ma: "projekt", "filetype", "rok", etc.
> - to je taky `E/A/V` triplet: `Entita` je ten objekt, `Attribut` je neco jako `IS_A` a `Value` je odkaz na kategorii - ktera je taky objekt s `E/A/V` tripletama, znacici co musi objekt splnovat
## Input
> - pridavas soubory bud pres web rovnou do databaze, nebo syncthingoidne do filetree, a pak zarazujes
## Output
> - output je bud ten, ze je ven exposly jakysi APIcko, ktery ti dava jenom pristup do jedny z moznejch hierarchii, a s tim pracuje treba radio, nebo photo uploader, nebo OCRko
> - nebo ten, ze to proste pouzivas misto file browseru, ale kdykoli mas moznost se vratit zpatky na baseline [[filesystem]] kdyz najdes, co hledas

> (pravdepodobne useless pro kohokoli jinyho)
2020-10-30 10:22:55 +01:00
> (clarification - neni to teda jenom key/value, zjistil jsem ze se tomu rika entity/attribute/value, kdy ten key/value je jenom ta posledni dvojice, a "entity" je nejakej abstraktni anchor ke kterymu se pojej ruzny key/values; moje pointa je, ze entity nemusi bejt enom IDcko na ktery vazes, ale i primo data, ktery muzou existovat tim padem na vic mistech / jako vic filu zaroven (nebo taky zadny), a i ty samotny vztahy mezi entitama, cimz ti vznika moznost i nejak znackovat co vlastne o tech datech rikas)
# Goals
- ~~democratic user interface model a la Syncthing~~
- ~~Content-Addressability~~
- ~~K/V metadata store~~
- schemas / constraints on metadata
- (auto-admin?)
- Links between objects
- 1-way = Tags
- 2-way = Relations
- ~~3-way = ???~~
- 1st order tags
- 1st order links (?)
- kompozice souboru
2020-11-05 11:00:58 +01:00
- skrz schemata! (sub-objekty pojici se k jedne ci vice entitam)
2020-10-30 10:22:55 +01:00
- Modes
- R/O only
- Hybrid
- Full
- FS revisions / metadata only backups
- staging area, queues...

# Information enters, is processed
![[mapping_language.png]]
# Random (and outdated) points
- content-addressability
- hidden structure within filetypes
- breaking apart from a hirearchy
- key/value store protocol // backend
- VFS compat layer
- config keys as files
- FS as a rich API
- syncthing model, sidecar files
- S3 API ?
