Tool presentation

Hypothesis: the Descriptor Models already exist for the project

■Two parts Descriptors creation and POT visualisation (during the Formal Definition Phase)

Plan first design Easy filling up of Descriptors,

Centralized information POT creation and validation POT visualization With easy GUI

Transfer follow-up and visualisation (during the Transfer Phase)

Follow-up Descriptor state in POT and follow-up detail visualization Using the same graphical visualisation and POT information

The current version of the prototype doesn’t take into account the SIP part (regrouping and sequencing constraints, …)

Plan of Transfer: description

■The POT Tree a tree made of nodes and leaves

nodes leaves

each node/leaf is associated with an XSD descriptor (Descriptor Model) an XML file (Descriptor)

used during the phases Formal Definition Transfer (and Validation)

PAIS tool – 12-13 June 2006

■ Elementary Plan design (descriptor_model_ID, descriptor_ID, title) using the list of Descriptor Models: creation of nodes and first graphical view without need to give further Object information

■ Descriptors creation: node instantiation (possible to do it in several times with automatic base updates) and validation (XAmple form). The XML files thus created populate the ingest base (complete view on the nodes of the POT and the links between these nodes)

■ Graphic representation of the POT which can be seen and understood by the Producer and the Archive

POT design: main functionalities (2/2)

■Node actions

Add node

Delete node

Modify node

Node definition

Unique identifier (Id)

Label

Descriptor Model (.XSD file)

PAIS tool – 12-13 June 2006

POT Design : Node Actions (1/2)

■Add node

leaf becomes a node

default generated id, label and model descriptor

unique id accepted

■Delete node

remove the node and all children

ask confirmation when node, or children nodes is/are XAmple modified

PAIS tool – 12-13 June 2006

POT Design : Node Actions (2/2)

■Modify node open Xample editor use the Descriptor Model information automatically fills the following data

descriptor_ID descriptor_type parent_collection

Allows to complete other data fields Related_descriptor_ID

– Used with "Show Linked Nodes"
