> Memos are documents. Collections group memos and set who sees them. Notebooks group memos inside a collection. A workspace holds it all for a team. # How Fieldwerk is organised Fieldwerk has four layers, from small to large. Knowing them tells you where to put something so your team and your AI can find it later, and who will be able to see it: - A **memo** is a document with its own link. One idea, one meeting, one plan. - A **collection** groups related memos and decides who can see them. It isn't a folder, because a memo can be in several collections at once. - A **notebook** is a smaller group inside a collection, such as one client or one quarter. - A **workspace** holds all of it for a person or a team, with its own members and plan. Files, views and properties sit alongside these. If you only remember one thing, put each memo in a collection and give the collection standing instructions, so people and their AI file and find things the same way. [Fieldwerk's layers (interactive content, see the page)](https://help.fieldwerk.ai/duysi66dh8/how-fieldwerk-is-organised) ## Memos A memo is a plain Markdown document with text, headings, lists, tables, images and tasks. Each one has a single link, and you choose what that link allows. Several people, and their AI, can edit the same memo at once, and every change is kept in its history, so you can always see who changed what and go back. A memo can carry its own properties, kept as front matter at the top of its Markdown. These memo properties travel with it into every collection it's in. See [Create and edit a memo](https://help.fieldwerk.ai/bviloypu9k/create-and-edit-a-memo.md). ## Collections A collection is a group of memos about one thing, such as a project, a client or a team handbook. It is the unit you share and the unit your AI works in. A memo can be in several collections. Collections carry: - **Access**: who can view, comment, edit or manage it. - **Properties**: collection properties like status or owner that every memo in it can have. A memo's values for them belong to this collection, so the same memo can have a different status in another collection. - **Views**: lists, boards, tables, calendars, timelines and canvases. - **Instructions**: how the collection should be used, for people and their AI. Your AI reads them before it files or edits anything there. ![A workspace's collections in the sidebar, with the Website relaunch collection open and its memos shown in a List view, beside its By stage and Tracker views](https://img.fieldwerk.ai/memos/xlmlt409gp/6a0e32c672fcbcfdf4abe6e2@2x.png?px=1440) See [Organise memos into collections](https://help.fieldwerk.ai/saoun9xu7f/organise-memos-into-collections.md). ## Notebooks A notebook groups memos and files inside one collection, for example one per client or per quarter. It has its own views and instructions, and its data files can feed an artifact. See [Group memos inside a collection with notebooks](https://help.fieldwerk.ai/0ze3d1lmmz/group-memos-inside-a-collection.md). ## Workspaces A workspace is the home for a person or a team. It has members, a plan and settings. People in a workspace can be full members, limited members who see only chosen collections, or guests who see only chosen memos. You can belong to several workspaces and switch between them from the sidebar. See [How member types work](https://help.fieldwerk.ai/sx2fr6z3n6/how-member-types-work.md). ## Files, views and properties - **Files and links** sit beside memos in a collection or notebook, or are attached to a memo. See [Add files and links](https://help.fieldwerk.ai/7em790nrmb/add-files-and-links.md). - **Properties** are the values you track, either on the memo itself or in a collection. See [Track work with properties](https://help.fieldwerk.ai/hp1532ap47/track-work-with-properties.md). - **Views** show a collection in different ways. See [See a collection as a list, board, table, calendar or timeline](https://help.fieldwerk.ai/riqjfipirh/see-a-collection-as-a-list.md). ## Where things show up - **My memos**: memos you created. - **All collections**: collections you can open in this workspace. - **Shared with me**: memos people have shared with you directly, including from workspaces you're a guest in. - **Trash**: memos you've deleted, until their restore window ends. See [Lock, archive or delete a memo](https://help.fieldwerk.ai/0uxsg79ylw/lock-archive-or-delete-a-memo.md).
