![]() ![]() The CIP skid can be either a single or multi-tank framework depending on the applications. ![]() A guide is 1.5 ms -1 velocity which is then used in conjunction with the pipeline size to determine the size of the pump being used for the delivery of the chemicals. Pipeline cleaning is normally based on providing sufficient velocity in the pipeline for the turbulent motion of the fluid to dislodge the particles of the residue that need to be removed. The CIP skid will have a heating element for the water/ chemicals as elevated temperatures assist cleaning. There is normally a rinse cycle followed by cleaning, detergent wash, disinfection, rinse and final rinse. What is involved in CIP Cleaning?ĬIP cleaning is typically the preparation & delivery of cleaning agents. The CIP stands for Clean In Place and the cleaning agents can be water, water with dosed detergent or chemicals such as Caustic/Acid or oils depending on the cleaning duties and end user duties. For a given Content Type, any requirements or restrictions on the type of content that can be contained in the SIP will be described in that Content Type's Preservation Action Plan.CIP Skids are an actual framework and mechanism of delivering the cleaning agents to the pipeline or tanks that are used in production by Pharmaceutical / Dairy / Food producers.The format of the SIP may vary from submitter to submitter, based on the submitters willingness and ability to provide the content and metadata in a specific format.The information package that is delivered to McMaster University digital repositories for use in the construction of one or more AIPs.In turn, the AIP contains metadata tying it back to the SIP. The DIP is retrieved using the URI for the corresponding AIP.Context information is provided in the form of links to other items in a given collection. ![]() Depending on the level of access, a user can see basic object metadata and a link to the object article as available.User access to archival objects is generally provided through the McMaster University Digital Archive website.McMaster University Library's DIPs are always generated from a single AIP.OAIS describes a DIP as "the Information Package, derived from a part, or all, of one or more AIPs, received by the Consumer in response to a request to the OAIS.".In all cases, the descriptive metadata will be recreated within the preservation metadata. McMaster University Library preservation metadata packages both the descriptive and preservation metadata together.ĭepending on the type of CDO, the format of this descriptive metadata can vary (MODS or Dublin Core), but is selected to maximize findability. This information can be used to determine integrity of an object being copied within the system (as in the case of a change in storage location), or for periodic integrity checks. Examples of these relationships can include: a newer version of an object that supersedes an older one.įixity Information - Fixity information is generated at the time of ingest in order to later determine whether or not the item remains in the same state as when it was ingested. Provenance Information - Provenance metadata is maintained for each object that provides a history of preservation events in the object's lifetime, beginning at ingest into the digital repositories and referencing any preservation activities taken on the object (e.g., replacement due to corruption, format migration, etc.).Ĭontext Information - As appropriate, information on how a CDO relates to other CDOs or to other conceptual entities. Reference Information - Identifiers are stored for each object identifying it globally (e.g. Preservation Description Information (PDI) Representation Information is maintained, and contains information on the CDO's file format, version, and a reference to a format registry in order to provide information on how to interpret the file. ![]() The Content Data Object (CDO) is generally stored with the primary preservation metadata file, which is held in Fedora Commons. This description will use the OAIS Information Model to illustrate completeness of our conceptual model, and will describe, in general terms, what a McMaster University Library AIP looks like. The level of content in a McMaster University Digital Archive AIP can vary, depending on the amount of content provided by the submitter. The information package consisting of the Content Information (CI), Preservation Description Information (PDI), Packaging Information (PI), and Descriptive Information (DI) that is archived at McMaster University Library. ![]()
